The mechanism used, to\n * activate support for map-based bindings at runtime is possible via the\n * `activeStylingMapFeature` function (which is also present in this file).\n *\n * # The Algorithm\n * Whenever a map-based binding updates (which is when the identity of the\n * map-value changes) then the map is iterated over and a `StylingMapArray` array\n * is produced. The `StylingMapArray` instance is stored in the binding location\n * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`\n * instruction were called. Once the binding changes, then the internal `bitMask`\n * value is marked as dirty.\n *\n * Styling values are applied once CD exits the element (which happens when\n * the `select(n)` instruction is called or the template function exits). When\n * this occurs, all prop-based bindings are applied. If a map-based binding is\n * present then a special flushing function (called a sync function) is made\n * available and it will be called each time a styling property is flushed.\n *\n * The flushing algorithm is designed to apply styling for a property (which is\n * a CSS property or a className value) one by one. If map-based bindings\n * are present, then the flushing algorithm will keep calling the maps styling\n * sync function each time a property is visited. This way, the flushing\n * behavior of map-based bindings will always be at the same property level\n * as the current prop-based property being iterated over (because everything\n * is alphabetically sorted).\n *\n * Let's imagine we have the following HTML template code:\n *\n * ```html\n * <div [style]=\"{width:'100px', height:'200px', 'z-index':'10'}\"\n *      [style.width.px]=\"200\">...</div>\n * ```\n *\n * When CD occurs, both the `[style]` and `[style.width]` bindings\n * are evaluated. Then when the styles are flushed on screen, the\n * following operations happen:\n *\n * 1. `[style.width]` is attempted to be written to the element.\n *\n * 2.  Once that happens, the algorithm instructs the map-based\n *     entries (`[style]` in this case) to \"catch up\" and apply\n *     all values up to the `width` value. When this happens the\n *     `height` value is applied to the element (since it is\n *     alphabetically situated before the `width` property).\n *\n * 3. Since there are no more prop-based entries anymore, the\n *    loop exits and then, just before the flushing ends, it\n *    instructs all map-based bindings to \"finish up\" applying\n *    their values.\n *\n * 4. The only remaining value within the map-based entries is\n *    the `z-index` value (`width` got skipped because it was\n *    successfully applied via the prop-based `[style.width]`\n *    binding). Since all map-based entries are told to \"finish up\",\n *    the `z-index` value is iterated over and it is then applied\n *    to the element.\n *\n * The most important thing to take note of here is that prop-based\n * bindings are evaluated in order alongside map-based bindings.\n * This allows all styling across an element to be applied in O(n)\n * time (a similar algorithm is that of the array merge algorithm\n * in merge sort).\n */\nvar syncStylingMap = function (context, renderer, element, data, applyStylingFn, sanitizer, mode, targetProp, defaultValue) {\n    var targetPropValueWasApplied = false;\n    // once the map-based styling code is activate it is never deactivated.

hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n// indirectly calls E1's ChangeDetectorRef.detectChanges().

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 * - `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 `<input>` elements that accept user input.

The default\n * template for the `else` clause is blank.\n *\n * A [shorthand form](guide/structural-directives#the-asterisk--prefix) of the directive,\n * `*ngIf=\"condition\"`, is generally used, provided\n * as an attribute of the anchor element for the inserted template.\n * Angular expands this into a more explicit version, in which the anchor element\n * is contained in an `<ng-template>` element.\n *\n * Simple form with shorthand syntax:\n *\n * ```\n * <div *ngIf=\"condition\">Content to render when condition is true.</div>\n * ```\n *\n * Simple form with expanded syntax:\n *\n * ```\n * <ng-template [ngIf]=\"condition\"><div>Content to render when condition is\n * true.</div></ng-template>\n * ```\n *\n * Form with an \"else\" block:\n *\n * ```\n * <div *ngIf=\"condition; else elseBlock\">Content to render when condition is true.</div>\n * <ng-template #elseBlock>Content to render when condition is false.</ng-template>\n * ```\n *\n * Shorthand form with \"then\" and \"else\" blocks:\n *\n * ```\n * <div *ngIf=\"condition; then thenBlock else elseBlock\"></div>\n * <ng-template #thenBlock>Content to render when condition is true.</ng-template>\n * <ng-template #elseBlock>Content to render when condition is false.</ng-template>\n * ```\n *\n * Form with storing the value locally:\n *\n * ```\n * <div *ngIf=\"condition as value; else elseBlock\">{{value}}</div>\n * <ng-template #elseBlock>Content to render when value is null.</ng-template>\n * ```\n *\n * @usageNotes\n *\n * The `*ngIf` directive is most commonly used to conditionally show an inline template,\n * as seen in the following  example.\n * The default `else` template is blank.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ### Showing an alternative template using `else`\n *\n * To display a template when `expression` evaluates to false, use an `else` template\n * binding as shown in the following example.\n * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.\n * The template can be defined anywhere in the component view, but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ### Using an external `then` template\n *\n * In the previous example, the then-clause template is specified inline, as the content of the\n * tag that contains the `ngIf` directive. You can also specify a template that is defined\n * externally, by referencing a labeled `<ng-template>` 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 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](guide/template-syntax#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 * <div class=\"hero-list\" *ngIf=\"heroes else loading\">\n *  ...\n * </div>\n *\n * <ng-template #loading>\n *  <div>Loading...</div>\n * </ng-template>\n * ```\n *\n * You can see that the \"else\" clause references the `<ng-template>`\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 `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `<ng-template>` tag.\n *\n * ```\n * <ng-template [ngIf]=\"hero-list\" [ngIfElse]=\"loading\">\n *  <div class=\"hero-list\">\n *   ...\n *  </div>\n * </ng-template>\n *\n * <ng-template #loading>\n *  <div>Loading...</div>\n * </ng-template>\n * ```\n *\n * The presence of the implicit template object has implications for the nesting of\n * structural directives.

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time 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: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n * @publicApi\n */\n// clang-format on\nvar DatePipe = /** @class */ (function () {\n    function DatePipe(locale) {\n        this.locale = locale;\n    }\n    DatePipe_1 = DatePipe;\n

It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n *\n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n *\n * ```ts\n * const selectedCountriesControl = new FormControl();\n * ```\n *\n * ```\n * <select [compareWith]=\"compareFn\"  [formControl]=\"selectedCountriesControl\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n *\n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n * }\n * ```\n *\n * **Note:** We listen to the 'change' event because 'input' events aren't fired\n * for selects in Firefox and IE:\n * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n *\n * @ngModule ReactiveFormsModule\n * @ngModule FormsModule\n * @publicApi\n */\nvar SelectControlValueAccessor = /** @class */ (function () {\n    function SelectControlValueAccessor(_renderer, _elementRef) {\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /** @internal */\n        this._optionMap = new Map();\n        /** @internal */\n        this._idCounter = 0;\n        /**\n         * @description\n         * The registered callback function called when a change event occurs on the input element.\n         */\n        this.onChange = function (_) { };\n        /**\n         * @description\n         * The registered callback function called when a blur event occurs on the input element.\n         */\n        this.onTouched = function () { };\n        this._compareWith = ɵlooseIdentical;\n    }\n    Object.defineProperty(SelectControlValueAccessor.prototype, \"compareWith\", {\n        /**\n         * @description\n         * Tracks the option comparison algorithm for tracking identities when\n         * checking for changes.\n         */\n        set: function (fn) {\n            if (typeof fn !== 'function') {\n                throw new Error(\"compareWith must be a function, but received \" + JSON.stringify(fn));\n            }\n            this._compareWith = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    /**\n     * Sets the \"value\" property on the input element.

Use the\n * `ngModel` selector to activate it.\n *\n * It accepts a domain model as an optional `Input`. If you have a one-way binding\n * to `ngModel` with `[]` syntax, changing the value of the domain model in the component\n * class sets the value in the view. If you have a two-way binding with `[()]` syntax\n * (also known as 'banana-box syntax'), the value in the UI always syncs back to\n * the domain model in your class.\n *\n * To inspect the properties of the associated `FormControl` (like validity state),\n * export the directive into a local template variable using `ngModel` as the key (ex: `#myVar=\"ngModel\"`).\n * You then access the control using the directive's `control` property,\n * but most properties used (like `valid` and `dirty`) fall through to the control anyway for direct access.\n * See a full list of properties directly available in `AbstractControlDirective`.\n *\n * @see `RadioControlValueAccessor`\n * @see `SelectControlValueAccessor`\n *\n * @usageNotes\n *\n * ### Using ngModel on a standalone control\n *\n * The following examples show a simple standalone control using `ngModel`:\n *\n * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}\n *\n * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute\n * so that the control can be registered with the parent form under that name.\n *\n * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,\n * as the parent form syncs the value for you. You access its properties by exporting it into a\n * local template variable using `ngForm` such as (`#f=\"ngForm\"`). Use the variable where\n * needed on form submission.\n *\n * If you do need to populate initial values into your form, using a one-way binding for\n * `ngModel` tends to be sufficient as long as you use the exported form's value rather\n * than the domain model's value on submit.\n *\n * ### Using ngModel within a form\n *\n * The following example shows controls using `ngModel` within a form:\n *\n * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}\n *\n * ### Using a standalone ngModel within a group\n *\n * The following example shows you how to use a standalone ngModel control\n * within a form.

The name attribute is used\n * within a custom form component, and the name `@Input` property serves a different purpose.\n *\n * ```html\n * <form>\n *   <my-person-control name=\"Nancy\" ngModel [ngModelOptions]=\"{name: 'user'}\">\n *   </my-person-control>\n * </form>\n * <!-- form value: {user: ''} -->\n * ```\n *\n * @ngModule FormsModule\n * @publicApi\n */\nvar NgModel = /** @class */ (function (_super) {\n    __extends(NgModel, _super);\n    function NgModel(parent, validators, asyncValidators, valueAccessors) {\n        var _this = _super.call(this) || this;\n        _this.control = new FormControl();\n        /** @internal */\n        _this._registered = false;\n        /**\n         * @description\n         * Event emitter for producing the `ngModelChange` event after\n         * the view model updates.\n         */\n        _this.update = new EventEmitter();\n        _this._parent = parent;\n        _this._rawValidators = validators || [];\n        _this._rawAsyncValidators = asyncValidators || [];\n        _this.valueAccessor = selectValueAccessor(_this, valueAccessors);\n        return _this;\n    }\n    /**\n     * @description\n     * A lifecycle method called when the directive's inputs change.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n * @publicApi\n */\nvar FormControlDirective = /** @class */ (function (_super) {\n    __extends(FormControlDirective, _super);\n    function FormControlDirective(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * @description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular `FormControlDirective` instance.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'})\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n * @publicApi\n */\nvar FormControlName = /** @class */ (function (_super) {\n    __extends(FormControlName, _super);\n    function FormControlName(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        _this._added = false;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * @description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.

Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.\n *\n * 3. Use the player object to control the animation programmatically.\n *\n * For example:\n *\n * ```ts\n * // import the service from BrowserAnimationsModule\n * import {AnimationBuilder} from '@angular/animations';\n * // require the service as a dependency\n * class MyCmp {\n *   constructor(private _builder: AnimationBuilder) {}\n *\n *   makeAnimation(element: any) {\n *     // first define a reusable animation\n *     const myAnimation = this._builder.build([\n *       style({ width: 0 }),\n *       animate(1000, style({ width: '100px' }))\n *     ]);\n *\n *     // use the returned factory object to create a player\n *     const player = myAnimation.create(element);\n *\n *     player.play();\n *   }\n * }\n * ```\n *\n * @publicApi\n */\nvar AnimationBuilder = /** @class */ (function () {\n    function AnimationBuilder() {\n    }\n    return AnimationBuilder;\n}());\n/**\n * A factory object returned from the `AnimationBuilder`.`build()` method.\n *\n * @publicApi\n */\nvar AnimationFactory = /** @class */ (function () {\n    function AnimationFactory() {\n    }\n    return AnimationFactory;\n}());\n\n/**\n * @license\n * Copyright Google Inc.

Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n * The following example defines a transition that starts by hiding the element,\n * then makes sure that it animates properly to whatever state is currently active for trigger:\n *\n * ```typescript\n * transition(\"void => *\", [\n *   style({ opacity: 0 }),\n *   animate(500)\n *  ])\n * ```\n * ### Boolean value matching\n * If a trigger binding value is a Boolean, it can be matched using a transition expression\n * that compares true and false or 1 and 0. For example:\n *\n * ```\n * // in the template\n * <div [@openClose]=\"open ? true : false\">...</div>\n * // in the component metadata\n * trigger('openClose', [\n *   state('true', style({ height: '*' })),\n *   state('false', style({ height: '0px' })),\n *   transition('false <=> true', animate(500))\n * ])\n * ```\n *\n * @publicApi\n **/\nfunction transition(stateChangeExpr, steps, options) {\n    if (options === void 0) { options = null; }\n    return { type: 1 /* Transition */, expr: stateChangeExpr, animation: steps, options: 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.
