` 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.

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.

The default\n * template for the `else` clause is blank.\n *\n * A [shorthand form](guide/structural-directives#asterisk) 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 `` element.\n *\n * Simple form with shorthand syntax:\n *\n * ```\n * Content to render when condition is true.

\n * Content to render when value is null.\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 `` 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 `` 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 *
\n * \n *\n * \n * Loading...
\n * \n * ```\n *\n * The presence of the implicit template object has implications for the nesting of\n * structural directives.

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

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: `\n *
Today is {{today | date}}
\n *
Or if you prefer, {{today | date:'fullDate'}}
\n *
The time is {{today | date:'h:mm a z'}}
