     * when used to format the number 12345.678 could result in "12'345,678". That would happen if the
     * grouping separator for your language is an apostrophe, and the decimal separator is a comma.
     *
     * <b>Important:</b> The characters `.` `,` `0` `#` (and others below) are special placeholders
     * that stand for the decimal separator, and so on, and are NOT real characters.
     * You must NOT "translate" the placeholders. For example, don't change `.` to `,` even though in
     * your language the decimal point is written with a comma. The symbols should be replaced by the
     * local equivalents, using the appropriate `NumberSymbol` for your language.
     *
     * Here are the special characters used in number patterns:
     *
     * | Symbol | Meaning |
     * |--------|---------|
     * | . | Replaced automatically by the character used for the decimal point. |
     * | , | Replaced by the "grouping" (thousands) separator. |
     * | 0 | Replaced by a digit (or zero if there aren't enough digits). |
     * | # | Replaced by a digit (or nothing if there aren't enough). |
     * | ¤ | Replaced by a currency symbol, such as $ or USD. |
     * | % | Marks a percent format. The % symbol may change position, but must be retained. |
     * | E | Marks a scientific format. The E symbol may change position, but must be retained. |
     * | ' | Special characters used as literal characters are quoted with ASCII single quotes. |

     * Instantiates a single {@link Component} type and inserts its Host View into current View.
     * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
     *
     * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
     * any existing component will get destroyed.
     *
     * @usageNotes
     *
     * ### Fine tune control
     *
     * You can control the component creation process by using the following optional attributes:
     *
     * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
     * the Component. Defaults to the injector of the current view container.
     *
     * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
     * section of the component, if exists.
     *
     * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow dynamically loading other
     * module, then load a component from that module.
     *
     * ### Syntax
     *
     * Simple
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
     * ```
     *
     * Customized injector/content
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression;
     *                                   injector: injectorExpression;
     *                                   content: contentNodesExpression;">
     * </ng-container>
     * ```
     *
     * Customized ngModuleFactory
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression;
     *                                   ngModuleFactory: moduleFactory;">
     * </ng-container>
     * ```
     *
     * ### A simple example

     * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}
     *

    /**
     * A [structural directive](guide/structural-directives) that renders
     * a template for each item in a collection.
     * The directive is placed on an element, which becomes the parent
     * of the cloned templates.
     *
     * The `ngForOf` directive is generally used in the
     * [shorthand form](guide/structural-directives#the-asterisk--prefix) `*ngFor`.
     * In this form, the template to be rendered for each iteration is the content
     * of an anchor element containing the directive.
     *
     * The following example shows the shorthand syntax with some options,
     * contained in an `<li>` element.
     *
     * ```
     * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
     * ```
     *
     * The shorthand form expands into a long form that uses the `ngForOf` selector
     * on an `<ng-template>` element.
     * The content of the `<ng-template>` element is the `<li>` element that held the
     * short-form directive.
     *
     * Here is the expanded version of the short-form example.
     *
     * ```
     * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
     *   <li>...</li>
     * </ng-template>
     * ```
     *
     * Angular automatically expands the shorthand syntax as it compiles the template.
     * The context for each embedded view is logically merged to the current component
     * context according to its lexical position.
     *
     * When using the shorthand syntax, Angular allows only [one structural directive
     * on an element](guide/structural-directives#one-structural-directive-per-host-element).
     * If you want to iterate conditionally, for example,
     * put the `*ngIf` on a container element that wraps the `*ngFor` element.
     * For futher discussion, see
     * [Structural Directives](guide/structural-directives#one-per-element).
     *
     * @usageNotes
     *
     * ### Local variables
     *
     * `NgForOf` provides exported values that can be aliased to local variables.
     * For example:
     *
     *  ```
     * <li *ngFor="let user of users; index as i; first as isFirst">
     *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
     * </li>
     * ```
     *
     * The following exported values can be aliased to local variables:
     *
     * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
     * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
     * more complex then a property access, for example when using the async pipe (`userStreams |
     * async`).
     * - `index: number`: The index of the current item in the iterable.
     * - `first: boolean`: True when the item is the first item in the iterable.
     * - `last: boolean`: True when the item is the last item in the iterable.
     * - `even: boolean`: True when the item has an even index in the iterable.
     * - `odd: boolean`: True when the item has an odd index in the iterable.
     *
     * ### Change propagation
     *
     * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
     *
     * * When an item is added, a new instance of the template is added to the DOM.
     * * When an item is removed, its template instance is removed from the DOM.
     * * When items are reordered, their respective templates are reordered in the DOM.
     *
     * Angular uses object identity to track insertions and deletions within the iterator and reproduce
     * those changes in the DOM. This has important implications for animations and any stateful
     * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
     * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
     * such as user input.
     * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
     *
     * The identities of elements in the iterator can change while the data does not.
     * This can happen, for example, if the iterator is produced from an RPC to the server, and that
     * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
     * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
     * elements were deleted and all new elements inserted).
     *
     * To avoid this expensive operation, you can customize the default tracking algorithm.
     * by supplying the `trackBy` option to `NgForOf`.
     * `trackBy` takes a function that has two arguments: `index` and `item`.
     * If `trackBy` is given, Angular tracks changes by the return value of the function.

    /**
     * A structural directive that conditionally includes a template based on the value of
     * an expression coerced to Boolean.
     * When the expression evaluates to true, Angular renders the template
     * provided in a `then` clause, and when  false or null,
     * Angular renders the template provided in an optional `else` clause. The default
     * template for the `else` clause is blank.
     *
     * A [shorthand form](guide/structural-directives#the-asterisk--prefix) of the directive,
     * `*ngIf="condition"`, is generally used, provided
     * as an attribute of the anchor element for the inserted template.
     * Angular expands this into a more explicit version, in which the anchor element
     * is contained in an `<ng-template>` element.
     *
     * Simple form with shorthand syntax:
     *
     * ```
     * <div *ngIf="condition">Content to render when condition is true.</div>
     * ```
     *
     * Simple form with expanded syntax:
     *
     * ```
     * <ng-template [ngIf]="condition"><div>Content to render when condition is
     * true.</div></ng-template>
     * ```
     *
     * Form with an "else" block:
     *
     * ```
     * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
     * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
     * ```
     *
     * Shorthand form with "then" and "else" blocks:
     *
     * ```
     * <div *ngIf="condition; then thenBlock else elseBlock"></div>
     * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
     * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
     * ```
     *
     * Form with storing the value locally:
     *
     * ```
     * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
     * <ng-template #elseBlock>Content to render when value is null.</ng-template>
     * ```
     *
     * @usageNotes
     *
     * The `*ngIf` directive is most commonly used to conditionally show an inline template,
     * as seen in the following  example.
     * The default `else` template is blank.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
     *
     * ### Showing an alternative template using `else`
     *
     * To display a template when `expression` evaluates to false, use an `else` template
     * binding as shown in the following example.
     * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
     * The template can be defined anywhere in the component view, but is typically placed right after
     * `ngIf` for readability.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfElse'}
     *
     * ### Using an external `then` template
     *
     * In the previous example, the then-clause template is specified inline, as the content of the
     * tag that contains the `ngIf` directive. You can also specify a template that is defined
     * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
     * change which template to use at runtime, as shown in the following example.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
     *
     * ### Storing a conditional result in a variable
     *
     * You might want to show a set of properties from the same object. If you are waiting
     * for asynchronous data, the object can be undefined.
     * In this case, you can use `ngIf` and store the result of the condition in a local
     * variable as shown in the the following example.
     *
     * {@example common/ngIf/ts/module.ts region='NgIfAs'}
     *
     * This code uses only one `AsyncPipe`, so only one subscription is created.
     * The conditional statement stores the result of `userStream|async` in the local variable `user`.
     * You can then bind the local `user` repeatedly.
     *
     * The conditional displays the data only if `userStream` returns a value,
     * so you don't need to use the
     * [safe-navigation-operator](guide/template-syntax#safe-navigation-operator) (`?.`)
     * to guard against null values when accessing properties.
     * You can display an alternative template while waiting for the data.
     *
     * ### Shorthand syntax
     *
     * The shorthand syntax `*ngIf` expands into two separate template specifications
     * for the "then" and "else" clauses. For example, consider the following shorthand statement,
     * that is meant to show a loading page while waiting for data to be loaded.
     *
     * ```
     * <div class="hero-list" *ngIf="heroes else loading">
     *  ...
     * </div>
     *
     * <ng-template #loading>
     *  <div>Loading...</div>
     * </ng-template>
     * ```
     *
     * You can see that the "else" clause references the `<ng-template>`
     * with the `#loading` label, and the template for the "then" clause
     * is provided as the content of the anchor element.
     *
     * However, when Angular expands the shorthand syntax, it creates
     * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
     * The anchor element containing the template for the "then" clause becomes
     * the content of this unlabeled `<ng-template>` tag.
     *
     * ```
     * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
     *  <div class="hero-list">
     *   ...
     *  </div>
     * </ng-template>
     *
     * <ng-template #loading>
     *  <div>Loading...</div>
     * </ng-template>
     * ```
     *
     * The presence of the implicit template object has implications for the nesting of
     * structural directives. For more on this subject, see
     * [Structural Directives](https://angular.io/guide/structural-directives#one-per-element).

     *
     * @description A structural directive that adds or removes templates (displaying or hiding views)
     * when the next match expression matches the switch expression.
     *
     * The `[ngSwitch]` directive on a container specifies an expression to match against.
     * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
     * - Every view that matches is rendered.
     * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
     * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
     * or `ngSwitchDefault` directive are preserved at the location.
     *
     * @usageNotes
     * Define a container element for the directive, and specify the switch expression
     * to match against as an attribute:
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">
     * ```
     *
     * Within the container, `*ngSwitchCase` statements specify the match expressions
     * as attributes. Include `*ngSwitchDefault` as the final case.
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">
     *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
     * ...
     *    <some-element *ngSwitchDefault>...</some-element>
     * </container-element>
     * ```
     *
     * ### Usage Examples
     *
     * The following example shows how to use more than one case to display the same view:
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">
     *   <!-- the same view can be shown in more than one case -->
     *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
     *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
     *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
     *   <!--default case when there are no matches -->
     *   <some-element *ngSwitchDefault>...</some-element>
     * </container-element>
     * ```
     *
     * The following example shows how cases can be nested:
     * ```
     * <container-element [ngSwitch]="switch_expression">
     *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
     *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
     *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
     *       <ng-container *ngSwitchCase="match_expression_3">
     *         <!-- use a ng-container to group multiple root nodes -->
     *         <inner-element></inner-element>
     *         <inner-other-element></inner-other-element>
     *       </ng-container>

     *
     * Formats a date value according to locale rules.
     *
     * Only the `en-US` locale data comes with Angular. To localize dates
     * in another language, you must import the corresponding locale data.
     * See the [I18n guide](guide/i18n#i18n-pipes) for more information.
     *
     * @see `formatDate()`
     *
     *
     * @usageNotes
     *
     * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
     * reformat the date on every change-detection cycle, treat the date as an immutable object
     * and change the reference when the pipe needs to run again.
     *
     * ### Pre-defined format options
     *
     * Examples are given in `en-US` locale.
     *
     * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).
     * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).
     * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM
     * GMT+1`).
     * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at
     * 9:03:01 AM GMT+01:00`).
     * - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).
     * - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).
     * - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).
     * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).
     * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).
     * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).
     * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).
     * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).
     *
     * ### Custom format options
     *
     * You can construct a format string using symbols to specify the components
     * of a date-time value, as described in the following table.
     * Format details depend on the locale.
     * Fields marked with (*) are only available in the extra data set for the given locale.

     *
     * Note that timezone correction is not applied to an ISO string that has no time component, such as "2016-09-19"
     *
     * ### Format examples
     *
     * These examples transform a date into various formats,
     * assuming that `dateObj` is a JavaScript `Date` object for
     * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
     * given in the local time for the `en-US` locale.
     *
     * ```
     * {{ dateObj | date }}               // output is 'Jun 15, 2015'
     * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
     * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
     * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
     * ```
     *
     * ### Usage example
     *
     * The following component uses a date pipe to display the current date in different formats.
     *
     * ```
     * @Component({
     *  selector: 'date-pipe',
     *  template: `<div>
     *    <p>Today is {{today | date}}</p>
     *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
     *    <p>The time is {{today | date:'h:mm a z'}}</p>
     *  </div>`
     * })
     * // Get the current date and time as a date-time value.
     * export class DatePipeComponent {
     *   today: number = Date.now();
     * }
     * ```
     *
