`Object.entries` is not supported in IE11 without a polyfill. The quickest,
most straightfoward fix for this is to simply use `Object.keys` instead.
We may want to consider including the polyfill in the CLI in the future
or just wait until IE11 support is dropped before using
`Object.entries`.

PR #34934 switched the `getting-started` docs example from using the
index of a product in the `products` array to using the product's ID
property for indentifiying each product in the `ProductDetailsComponent`
component. However, some necessary changes in the example code and the
`start-routing.md` guide were missed in #34934, resulting in broken
instructions for the readers (see #40189).
This commit is essentially a follow-up to #34934, making the remaining
changes in the example code and the guide instructions.

This commit does some minor clean-up in docregions of the

- Removes redundant docregion markers.
- Fixes whitespace inconsistencies.

a docregion (in order to avoid confusion).

During route activation, a componentless route will not have a context created
for it, but the logic continues to recurse so that children are still
activated. This can be seen here:
https://github.com/angular/angular/blob/362f45c4bf1bb49a90b014d2053f4c4474d132c0/packages/router/src/operators/activate_routes.ts#L151-L158
The current deactivation logic does not currently account for componentless routes.
This commit adjusts the deactivation logic so that if a context cannot
be retrieved for a given route (because it is componentless), we
continue to recurse and deactivate the children using the same
`parentContexts` in the same way that activation does.

CSS supports escaping in selectors, e.g. writing `.foo:bar` will match an element with the
`foo` class and `bar` pseudo-class, but `.foo\:bar` will match the `foo:bar` class. Our
shimmed shadow DOM encapsulation always assumes that `:` means a pseudo selector
which breaks a selector like `.foo\:bar`.
These changes add some extra logic so that escaped characters in selectors are preserved.
Fixes#31844.

In some browsers, notably a mobile version of webkit on iPad, the
result of calling `DOMParser.parseFromString()` returns a document
whose `body` property is null until the next tick of the browser.
Since this is of no use to us for sanitization, we now fall back to the
"inert document" strategy for this case.

Currently we check whether a property binding contains an interpolation using a regex so
that we can throw an error. The problem is that the regex doesn't account for quotes
which means that something like `[prop]="'{{ foo }}'"` will be considered an error, even
though it's not actually an interpolation.
These changes build on top of the logic from #39826 to account for interpolation
characters inside quotes.

When talking about parameter inheritance, one might think that matrix
parameters can be inherited from the "parent" segment, or the segment
which appears immediately to the left. In reality, when we talk about
a "parent" in the `Router`, we mean the parent `Route` config. This
config may contain more than one segment and matrix parameters must
appear at the end or they do not "belong" to any config.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

The `applyRedirects` and `recognize` algorithms have the same overall goal:
match a `UrlTree` with the application's `Routes` config. There are a
few key functions in these algorithms which can be shared rather than
duplicated between the two. This also makes it easier to see how the two
are similar and where they diverge.
PR Close#40029
PR Close#40315
This commit updates the `recognize` algorithm to work with named outlets
which have empty path parents. For example, given the following config
```
const routes = [
{
path: '',
children: [
{path: 'a', outlet: 'aux', component: AuxComponent}
]}
];
```
The url `/(aux:a)` should match this config. In order to do so, we need
to allow the children of `UrlSegmentGroup`s to match a `Route` config
for a different outlet (in this example, the `primary`) when it's an
empty path. This should also *only* happen if we were unable to find a
match for the outlet in the level above. That is, the matching strategy
is to find the first `Route` in the list which _matches the given
outlet_. If we are unable to do that, then we allow empty paths from
other outlets to match and try to find some child there whose outlet
matches our segment.

This commit updates the `recognize` algorithm to return `null` when a
segment does not match a given config rather than throwing an error.
This makes the code much easier to follow because the "no match" result
has to be explicitly handled rather than catching the error in very
specific places.

When stepping through the `recognize` algorithm, it is much easier to
follow when using a simple `for...of` rather than the helper
`mapChildrenIntoArray` with the passed closure. The only special thing that
`mapChildrenIntoArray` does is ensure the primary route appears first.
This change will have no affect on the result because `processChildren` later calls
`sortActivatedRouteSnapshots`, which does the same thing.

DI providers can be defined via `useFactory` function, which may have arguments configured via `deps` array.
The `deps` array may contain DI flags represented by DI decorators (such as `@Self`, `@SkipSelf`, etc). Prior to this
commit, having the `@Host` decorator in `deps` array resulted in runtime error in Ivy. The problem was that the `@Host`
decorator was not taken into account while `useFactory` argument list was constructed, the `@Host` decorator was
treated as a token that should be looked up.
This commit updates the logic which prepares `useFactory` arguments to recognize the `@Host` decorator.

According to the [spec](https://html.spec.whatwg.org/#scroll-to-fragid),
we should attempt to set the browser focus after scrolling to a

outlined in the spec by finding a fallback target if the original is not
focusable. Instead, we simply attempt to focus the element by calling
`focus` on it, which will do nothing if the element is not focusable.

Internally we store lifecycle hooks in the format `[index, hook, index, hook]` and when
iterating over them, we check one place ahead to figure out whether we've hit found
a hook or an index. The problem is that the loop is set up to iterate up to `hooks.length`
which means that we may go out of bounds on the last iteration, depending on where
we started. This appears to happen under a specific set of circumstances where a
directive calls `detectChanges` from an input setter while it has `ngOnChanges` and
`ngAfterViewInit` hooks.
These changes resolve the issue by only iterating up to `length - 1` which guarantees that
we can always look one place ahead.
This appears to have regressed some time in version 10.

PR #39876 introduced an error where the `onDestroy` of `ComponentRef`

in dev mode we would freeze `TCleanup` to verify that no more

that `TCleanup` was always present in dev mode. In production the

code was incorrectly indented and would only run if `TCleanup` was
present causing this issue.
