` tags and, since they are the\n * same tag in the same position, we'd be able to avoid completely\n * re-rendering the subtree under them with a new DOM element and would just\n * call out to `patch` to handle reconciling their children and so on.\n *\n * 3. Check, for both windows, to see if the element at the beginning of the\n * window corresponds to the element at the end of the other window. This is\n * a heuristic which will let us identify _some_ situations in which\n * elements have changed position, for instance it _should_ detect that the\n * children nodes themselves have not changed but merely moved in the\n * following example:\n *\n * oldVNode: `
`\n * newVNode: `
`\n *\n * If we find cases like this then we also need to move the concrete DOM\n * elements corresponding to the moved children to write the re-order to the\n * DOM.\n *\n * 4. Finally, if VNodes have the `key` attribute set on them we check for any\n * nodes in the old children which have the same key as the first element in\n * our window on the new children. If we find such a node we handle calling\n * out to `patch`, moving relevant DOM nodes, and so on, in accordance with\n * what we find.\n *\n * Finally, once we've narrowed our 'windows' to the point that either of them\n * collapse (i.e. they have length 0) we then handle any remaining VNode\n * insertion or deletion that needs to happen to get a DOM state that correctly\n * reflects the new child VNodes. If, for instance, after our window on the old\n * children has collapsed we still have more nodes on the new children that\n * we haven't dealt with yet then we need to add them, or if the new children\n * collapse but we still have unhandled _old_ children then we need to make\n * sure the corresponding DOM nodes are removed.\n *\n * @param parentElm the node into which the parent VNode is rendered\n * @param oldCh the old children of the parent node\n * @param newVNode the new VNode which will replace the parent\n * @param newCh the new children of the parent node\n */\nconst updateChildren = (parentElm, oldCh, newVNode, newCh) => {\n let oldStartIdx = 0;\n let newStartIdx = 0;\n let idxInOld = 0;\n let i = 0;\n let oldEndIdx = oldCh.length - 1;\n let oldStartVnode = oldCh[0];\n let oldEndVnode = oldCh[oldEndIdx];\n let newEndIdx = newCh.length - 1;\n let newStartVnode = newCh[0];\n let newEndVnode = newCh[newEndIdx];\n let node;\n let elmToMove;\n while (oldStartIdx <= oldEndIdx && newStartIdx <= newEndIdx) {\n if (oldStartVnode == null) {\n // VNode might have been moved left\n oldStartVnode = oldCh[++oldStartIdx];\n }\n else if (oldEndVnode == null) {\n oldEndVnode = oldCh[--oldEndIdx];\n }\n else if (newStartVnode == null) {\n newStartVnode = newCh[++newStartIdx];\n }\n else if (newEndVnode == null) {\n newEndVnode = newCh[--newEndIdx];\n }\n else if (isSameVnode(oldStartVnode, newStartVnode)) {\n // if the start nodes are the same then we should patch the new VNode\n // onto the old one, and increment our `newStartIdx` and `oldStartIdx`\n // indices to reflect that.

...
\n * ```\n *\n * ### Using an inline function\n * The `transition` animation method also supports reading an inline function which can decide\n * if its associated animation should be run.\n *\n * ```typescript\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n string]: any}): boolean {\n * // notice that `element` and `params` are also available here\n * return toState == 'yes-please-animate';\n * }\n *\n * @Component({\n * selector: 'my-component',\n * templateUrl: 'my-component-tpl.html',\n * animations: [\n * trigger('myAnimationTrigger', [\n * transition(myInlineMatcherFn, [\n * // the animation sequence code\n * ]),\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"yes-please-animate\";\n * }\n * ```\n *\n * ### Disabling Animations\n * When true, the special animation control binding `@.disabled` binding prevents\n * all animations from rendering.\n * Place the `@.disabled` binding on an element to disable\n * animations on the element itself, as well as any inner animation triggers\n * within the element.\n *\n * The following example shows how to use this feature:\n *\n * ```typescript\n * @Component({\n * selector: 'my-component',\n * template: `\n *
\n * `,\n * animations: [\n * trigger(\"childAnimation\", [\n * // ...\n * ])\n * ]\n * })\n * class MyComponent {\n * isDisabled = true;\n * exp = '...';\n * }\n * ```\n *\n * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,\n * along with any inner animations.\n *\n * ### Disable animations application-wide\n * When an area of the template is set to have animations disabled,\n * **all** inner components have their animations disabled as well.\n * This means that you can disable all animations for an app\n * by placing a host binding set on `@.disabled` on the topmost Angular component.\n *\n * ```typescript\n * import {Component, HostBinding} from '@angular/core';\n *\n * @Component({\n * selector: 'app-component',\n * templateUrl: 'app.component.html',\n * })\n * class AppComponent {\n * @HostBinding('@.disabled')\n * public animationsDisabled = true;\n * }\n * ```\n *\n * ### Overriding disablement of inner animations\n * Despite inner animations being disabled, a parent animation can `query()`\n * for inner elements located in disabled areas of the template and still animate\n * them if needed. This is also the case for when a sub animation is\n * queried by a parent and then later animated using `animateChild()`.\n *\n * ### Detecting when an animation is disabled\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\n * an instance of an `AnimationEvent`. If animations are disabled,\n * the `.disabled` flag on the event is true.\n *\n * @publicApi\n */\nfunction trigger(name, definitions) {\n return { type: 7 /* Trigger */, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\n * @param timings Sets `AnimateTimings` for the parent animation.\n * A string in the format \"duration [delay] [easing]\".\n * - Duration and delay are expressed as a number and optional time unit,\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\n * The default unit is milliseconds.\n * - The easing value controls how the animation accelerates and decelerates\n * during its runtime.

\n *\n * Be careful about entering end leaving elements as their transitions present a common\n * pitfall for developers.\n *\n * Note that when an element with a trigger enters the DOM its `:enter` transition always\n * gets executed, but its `:leave` transition will not be executed if the element is removed\n * alongside its parent (as it will be removed \"without warning\" before its transition has\n * a chance to be executed, the only way that such transition can occur is if the element\n * is exiting the DOM on its own).\n *\n *\n *
\n *\n * ### Animating to a Final State\n *\n * If the final step in a transition is a call to `animate()` that uses a timing value\n * with no `style` data, that step is automatically considered the final animation arc,\n * for the element to reach the final state, in such case Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n *\n * ### Usage Examples\n *\n * - Transition animations applied based on\n * the trigger's expression value\n *\n * ```HTML\n *
\n * ...\n *
\n * ```\n *\n * ```typescript\n * trigger(\"myAnimationTrigger\", [\n * ..., // states\n * transition(\"on => off, open => closed\", animate(500)),\n * transition(\"* <=> error\", query('.indicator', animateChild()))\n * ])\n * ```\n *\n * - Transition animations applied based on custom logic dependent\n * on the trigger's expression value and provided parameters\n *\n * ```HTML\n *
\n * ...\n *
\n * ```\n *\n * ```typescript\n * trigger(\"myAnimationTrigger\", [\n * ..., // states\n * transition(\n * (fromState, toState, _element, params) =>\n * ['firststep', 'laststep'].includes(fromState.toLowerCase())\n * && toState === params?.['target'],\n * animate('1s')\n * )\n * ])\n * ```\n *\n * @publicApi\n **/\nfunction transition(stateChangeExpr, steps, options = null) {\n return { type: 1 /* Transition */, expr: stateChangeExpr, animation: steps, options };\n}\n/**\n * Produces a reusable animation that can be invoked in another animation or sequence,\n * by calling the `useAnimation()` function.\n *\n * @param steps One or more animation objects, as returned by the `animate()`\n * or `sequence()` function, that form a transformation from one state to another.\n * A sequence is used by default when you pass an array.\n * @param options An options object that can contain a delay value for the start of the\n * animation, and additional developer-defined parameters.\n * Provided values for additional parameters are used as defaults,\n * and override values can be passed to the caller on invocation.\n * @returns An object that encapsulates the animation data.\n *\n * @usageNotes\n * The following example defines a reusable animation, providing some default parameter\n * values.\n *\n * ```typescript\n * var fadeAnimation = animation([\n * style({ opacity: '{{ start }}' }),\n * animate('{{ time }}',\n * style({ opacity: '{{ end }}'}))\n * ],\n * { params: { time: '1000ms', start: 0, end: 1 }});\n * ```\n *\n * The following invokes the defined animation with a call to `useAnimation()`,\n * passing in override parameter values.\n *\n * ```js\n * useAnimation(fadeAnimation, {\n * params: {\n * time: '2s',\n * start: 1,\n * end: 0\n * }\n * })\n * ```\n *\n * If any of the passed-in parameter values are missing from this call,\n * the default values are used.

For example:\n *\n * ```typescript\n * query(':self, .record:enter, .record:leave, @subTrigger', [...])\n * ```\n *\n * The `query()` function collects multiple elements and works internally by using\n * `element.querySelectorAll`. Use the `limit` field of an options object to limit\n * the total number of items to be collected. For example:\n *\n * ```js\n * query('div', [\n * animate(...),\n * animate(...)\n * ], { limit: 1 })\n * ```\n *\n * By default, throws an error when zero items are found. Set the\n * `optional` flag to ignore this error. For example:\n *\n * ```js\n * query('.some-element-that-may-not-be-there', [\n * animate(...),\n * animate(...)\n * ], { optional: true })\n * ```\n *\n * ### Entering and Leaving Elements\n *\n * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones\n * that can are those that Angular assumes can enter/leave based on their own logic\n * (if their insertion/removal is simply a consequence of that of their parent they\n * should be queried via a different token in their parent's `:enter`/`:leave` transitions).\n *\n * The only elements Angular assumes can enter/leave based on their own logic (thus the only\n * ones that can be queried via the `:enter` and `:leave` tokens) are:\n * - Those inserted dynamically (via `ViewContainerRef`)\n * - Those that have a structural directive (which, under the hood, are a subset of the above ones)\n *\n *
\n *\n * Note that elements will be successfully queried via `:enter`/`:leave` even if their\n * insertion/removal is not done manually via `ViewContainerRef`or caused by their structural\n * directive (e.g. they enter/exit alongside their parent).\n *\n *
\n *\n *
\n *\n * There is an exception to what previously mentioned, besides elements entering/leaving based on\n * their own logic, elements with an animation trigger can always be queried via `:leave` when\n * their parent is also leaving.\n *\n *
\n *\n * ### Usage Example\n *\n * The following example queries for inner elements and animates them\n * individually using `animate()`.\n *\n * ```typescript\n * @Component({\n * selector: 'inner',\n * template: `\n *

Overlap of animations\n * Given that a CSS property cannot be animated in more than one place at the same time, it's\n * important that this behavior is detected and validated.

Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3. Offset Validation\n * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n * Offsets within keyframes() are considered valid when:\n *\n * - No offsets are used at all\n * - Each style() entry contains an offset value\n * - Each offset is between 0 and 1\n * - Each offset is greater to or equal than the previous one\n *\n * Otherwise an error will be thrown.\n */\nfunction buildAnimationAst(driver, metadata, errors, warnings) {\n return new AnimationAstBuilderVisitor(driver).build(metadata, errors, warnings);\n}\nconst ROOT_SELECTOR = '';\nclass AnimationAstBuilderVisitor {\n constructor(_driver) {\n this._driver = _driver;\n }\n build(metadata, errors, warnings) {\n const context = new AnimationAstBuilderContext(errors);\n this._resetContextStyleTimingState(context);\n const ast = visitDslNode(this, normalizeAnimationEntry(metadata), context);\n if (context.unsupportedCSSPropertiesFound.size) {\n pushUnrecognizedPropertiesWarning(warnings, [...context.unsupportedCSSPropertiesFound.keys()]);\n }\n return ast;\n }\n _resetContextStyleTimingState(context) {\n context.currentQuerySelector = ROOT_SELECTOR;\n context.collectedStyles = {};\n context.collectedStyles[ROOT_SELECTOR] = {};\n context.currentTime = 0;\n }\n visitTrigger(metadata, context) {\n let queryCount = context.queryCount = 0;\n let depCount = context.depCount = 0;\n const states = [];\n const transitions = [];\n if (metadata.name.charAt(0) == '@') {\n context.errors.push(invalidTrigger());\n }\n metadata.definitions.forEach(def => {\n this._resetContextStyleTimingState(context);\n if (def.type == 0 /* State */) {\n const stateDef = def;\n const name = stateDef.name;\n name.toString().split(/\\s*,\\s*/).forEach(n => {\n stateDef.name = n;\n states.push(this.visitState(stateDef, context));\n });\n stateDef.name = name;\n }\n else if (def.type == 1 /* Transition */) {\n const transition = this.visitTransition(def, context);\n queryCount += transition.queryCount;\n depCount += transition.depCount;\n transitions.push(transition);\n }\n else {\n context.errors.push(invalidDefinition());\n }\n });\n return {\n type: 7 /* Trigger */,\n name: metadata.name,\n states,\n transitions,\n queryCount,\n depCount,\n options: null\n };\n }\n visitState(metadata, context) {\n const styleAst = this.visitStyle(metadata.styles, context);\n const astParams = (metadata.options && metadata.options.params) || null;\n if (styleAst.containsDynamicStyles) {\n const missingSubs = new Set();\n const params = astParams || {};\n styleAst.styles.forEach(value => {\n if (isObject(value)) {\n const stylesObj = value;\n Object.keys(stylesObj).forEach(prop => {\n extractStyleParams(stylesObj[prop]).forEach(sub => {\n if (!params.hasOwnProperty(sub)) {\n missingSubs.add(sub);\n }\n });\n });\n }\n });\n if (missingSubs.size) {\n const missingSubsArr = iteratorToArray(missingSubs.values());\n context.errors.push(invalidState(metadata.name, missingSubsArr));\n }\n }\n return {\n type: 0 /* State */,\n name: metadata.name,\n style: styleAst,\n options: astParams ?

This means\n * that when functional composition mix of these functions is evaluated (like in the example above)\n * then it will end up producing a tree of objects representing the animation itself.\n *\n * When this animation object tree is processed by the visitor code below it will visit each of the\n * verb statements within the visitor. And during each visit it will build the context of the\n * animation keyframes by interacting with the `TimelineBuilder`.\n *\n * [TimelineBuilder]\n * This class is responsible for tracking the styles and building a series of keyframe objects for a\n * timeline between a start and end time. The builder starts off with an initial timeline and each\n * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a\n * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n * they are complete.\n *\n * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergeSort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```\n * sequence([\n * style({ width: 0 }),\n * animate(1000, style({ width: 100 })),\n * animate(1000, style({ width: 200 })),\n * animate(1000, style({ width: 300 }))\n * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe\n * styles is an object that prototypically inherits from the backFill object, this means that if a\n * value is added into the backFill then it will automatically propagate any missing values to all\n * keyframes. Therefore the missing `height` value will be properly filled into the already\n * processed keyframes.\n *\n * When a sub-timeline is created it will have its own backFill property. This is done so that\n * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n * keyframes\n *\n * (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)\n *\n * [Validation]\n * The code in this file is not responsible for validation. That functionality happens with within\n * the `AnimationValidatorVisitor` code.\n */\nfunction buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles = {}, finalStyles = {}, options, subInstructions, errors = []) {\n return new AnimationTimelineBuilderVisitor().buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors);\n}\nclass AnimationTimelineBuilderVisitor {\n buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors = []) {\n subInstructions = subInstructions || new ElementInstructionMap();\n const context = new AnimationTimelineContext(driver, rootElement, subInstructions, enterClassName, leaveClassName, errors, []);\n context.options = options;\n context.currentTimeline.setStyles([startingStyles], null, context.errors, options);\n visitDslNode(this, ast, context);\n // this checks to see if an actual animation happened\n const timelines = context.timelines.filter(timeline => timeline.containsAnimation());\n if (Object.keys(finalStyles).length) {\n // note: we just want to apply the final styles for the rootElement, so we do not\n // just apply the styles to the last timeline but the last timeline which\n // element is the root one (basically `*`-styles are replaced with the actual\n // state style values only for the root element)\n let lastRootTimeline;\n for (let i = timelines.length - 1; i >= 0; i--) {\n const timeline = timelines[i];\n if (timeline.element === rootElement) {\n lastRootTimeline = timeline;\n break;\n }\n }\n if (lastRootTimeline && !lastRootTimeline.allowOnlyTimelineStyles()) {\n lastRootTimeline.setStyles([finalStyles], null, context.errors, options);\n }\n }\n return timelines.length ?

Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `count: number`: The length of the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ### Change propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls that are present, such as `` elements that accept user input. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).\n *\n * The identities of elements in the iterator can change while the data does not.\n * This can happen, for example, if the iterator is produced from an RPC to the server, and that\n * RPC is re-run. Even if the data hasn't changed, the second response produces objects with\n * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old\n * elements were deleted and all new elements inserted).\n *\n * To avoid this expensive operation, you can customize the default tracking algorithm.\n * by supplying the `trackBy` option to `NgForOf`.\n * `trackBy` takes a function that has two arguments: `index` and `item`.\n * If `trackBy` is given, Angular tracks changes by the return value of the function.\n *\n * @see [Structural Directives](guide/structural-directives)\n * @ngModule CommonModule\n * @publicApi\n */\nclass NgForOf {\n constructor(_viewContainer, _template, _differs) {\n this._viewContainer = _viewContainer;\n this._template = _template;\n this._differs = _differs;\n this._ngForOf = null;\n this._ngForOfDirty = true;\n this._differ = null;\n }\n /**\n * The value of the iterable expression, which can be used as a\n * [template input variable](guide/structural-directives#shorthand).\n */\n set ngForOf(ngForOf) {\n this._ngForOf = ngForOf;\n this._ngForOfDirty = true;\n }\n /**\n * Specifies a custom `TrackByFunction` to compute the identity of items in an iterable.\n *\n * If a custom `TrackByFunction` is not provided, `NgForOf` will use the item's [object\n * identity](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is)\n * as the key.\n *\n * `NgForOf` uses the computed key to associate items in an iterable with DOM elements\n * it produces for these items.\n *\n * A custom `TrackByFunction` is useful to provide good user experience in cases when items in an\n * iterable rendered using `NgForOf` have a natural identifier (for example, custom ID or a\n * primary key), and this iterable could be updated with new object instances that still\n * represent the same underlying entity (for example, when data is re-fetched from the server,\n * and the iterable is recreated and re-rendered, but most of the data is still the same).\n *\n * @see `TrackByFunction`\n */\n set ngForTrackBy(fn) {\n if ((typeof ngDevMode === 'undefined' || ngDevMode) && fn != null && typeof fn !== 'function') {\n // TODO(vicb): use a log service once there is a public one available\n if (console && console.warn) {\n console.warn(`trackBy must be a function, but received ${JSON.stringify(fn)}. ` +\n `See https://angular.io/api/common/NgForOf#change-propagation for more information.`);\n }\n }\n this._trackByFn = fn;\n }\n get ngForTrackBy() {\n return this._trackByFn;\n }\n /**\n * A reference to the template that is stamped out for each item in the iterable.\n * @see [template reference variable](guide/template-reference-variables)\n */\n set ngForTemplate(value) {\n // TODO(TS2.1): make TemplateRef>> once we move to TS v2.1\n // The current type is too restrictive; a template that just uses index, for example,\n // should be acceptable.\n if (value) {\n this._template = value;\n }\n }\n /**\n * Applies the changes when needed.\n * @nodoc\n */\n ngDoCheck() {\n if (this._ngForOfDirty) {\n this._ngForOfDirty = false;\n // React on ngForOf changes only once all inputs have been initialized\n const value = this._ngForOf;\n if (!this._differ && value) {\n if (typeof ngDevMode === 'undefined' || ngDevMode) {\n try {\n // CAUTION: this logic is duplicated for production mode below, as the try-catch\n // is only present in development builds.\n this._differ = this._differs.find(value).create(this.ngForTrackBy);\n }\n catch (_a) {\n throw new Error(`Cannot find a differ supporting object '${value}' of type '${getTypeName(value)}'.

You can also specify a template that is defined\n * externally, by referencing a labeled `` element. When you do this, you can\n * change which template to use at runtime, as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ### Storing a conditional result in a variable\n *\n * You might want to show a set of properties from the same object. If you are waiting\n * for asynchronous data, the object can be undefined.\n * In this case, you can use `ngIf` and store the result of the condition in a local\n * variable as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * This code uses only one `AsyncPipe`, so only one subscription is created.\n * The conditional statement stores the result of `userStream|async` in the local variable `user`.\n * You can then bind the local `user` repeatedly.\n *\n * The conditional displays the data only if `userStream` returns a value,\n * so you don't need to use the\n * safe-navigation-operator (`?.`)\n * to guard against null values when accessing properties.\n * You can display an alternative template while waiting for the data.\n *\n * ### Shorthand syntax\n *\n * The shorthand syntax `*ngIf` expands into two separate template specifications\n * for the \"then\" and \"else\" clauses. For example, consider the following shorthand statement,\n * that is meant to show a loading page while waiting for data to be loaded.\n *\n * ```\n * \n * ...\n *
\n *\n * \n * Loading...
\n * \n * ```\n *\n * You can see that the \"else\" clause references the ``\n * with the `#loading` label, and the template for the \"then\" clause\n * is provided as the content of the anchor element.\n *\n * However, when Angular expands the shorthand syntax, it creates\n * another `` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `` tag.\n *\n * ```\n * \n * \n * ...\n *

according to locale rules.\n *\n * `DatePipe` is executed only when it detects a pure change to the input value.\n * A pure change is either a change to a primitive input value\n * (such as `String`, `Number`, `Boolean`, or `Symbol`),\n * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).\n *\n * Note that mutating a `Date` object does not cause the pipe to be rendered again.\n * To ensure that the pipe is executed, you must create a new `Date` object.\n *\n * Only the `en-US` locale data comes with Angular. To localize dates\n * in another language, you must import the corresponding locale data.\n * See the [I18n guide](guide/i18n-common-format-data-locale) for more information.\n *\n * The time zone of the formatted value can be specified either by passing it in as the second\n * parameter of the pipe, or by setting the default through the `DATE_PIPE_DEFAULT_TIMEZONE`\n * injection token. The value that is passed in as the second parameter takes precedence over\n * the one defined using the injection token.\n *\n * @see `formatDate()`\n *\n *\n * @usageNotes\n *\n * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to\n * reformat the date on every change-detection cycle, treat the date as an immutable object\n * and change the reference when the pipe needs to run again.\n *\n * ### Pre-defined

for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }} // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }} // output is '9:43 PM'\n * {{ dateObj | date:'mm:ss' }} // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * @Component({\n * selector: 'date-pipe',\n * template: `\n *
Today is {{today | date}}
\n *
Or if you prefer, {{today | date:'fullDate'}}
\n *
The time is {{today | date:'h:mm a z'}}
