There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character
So back to the frog eyes we go.

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:
BEFORE:
elementStyling()
elementStyleProp()
elementClassProp()
elementStyleMap()
elementClassMap()
elementStylingApply()
AFTER:
styling()
styleProp()
classProp()
styleMap()
classMap()
stylingApply()

This patch is one commit of many patches that will unify all styling instructions
across both template-level bindings and host-level bindings. This patch in particular
removes the `elementIndex` param because it is already set prior to each styling
instruction via the `select(n)` instruction.

The web_worker images example is currently not really usable
because the rendered button that can be used to upload
an "image" to the demo is currently not working. This is because

Currently all playground examples are built with NGC, and most
of the HTML resources are automatically inlined. Surprisingly NGC
is able to resolve the relative component assets even though these
aren't specified in the `assets`. This seems to work because NGC
resolves the files in the execroot where the files are present
(if Bazel doesn't use sandboxing).

The `web_workers/images` example is not being tested by any e2e
spec and therefore it's technically not necessary to fix that it uses
external resources, though in order to ensure that the Bazel builds
are hermetic and that we can eventually add e2e specs for the
web_worker/image example, we should avoid any use of external
resources.
We remove the `web-animations` polyfill in the `web_workers/animations`
example because we should try to vendor as few as possible deps. Also
the animations API is already supported by browsers we run the e2e tests
against (note here: `web_workers/animations` is currently also disabled)

Currently when someone serves the "person_management" playground
example, there will be runtime exceptions by `@angular/forms` if
someone clicks on one of the two buttons rendered in the example.
This happens because the example is outdated and the input elements
using `ngModel` do not specify a proper "name" while being inside of
a `<form>` element. A name is required inside of a form. The failure
is not specific to Ivy and is not covered by any test because the e2e
tests for this example are just asserting that the page properly loads
(the error only shows up one of the buttons has been clicked)
This is the reason why these errors were never visibile to the e2e tests.

so that the example can work as expected.

PR Close#26139
Previously in Ivy, metadata for directives/components/modules/etc was
carried in .d.ts files inside type information encoded on the
DirectiveDef, ComponentDef, NgModuleDef, etc types of Ivy definition
fields. This works well, but has the side effect of complicating Ivy's
runtime code as these extra generic type parameters had to be specified
as <any> throughout the codebase. *DefInternal types were introduced
previously to mitigate this issue, but that's the wrong way to solve
the problem.
This commit returns *Def types to their original form, with no metadata
attached. Instead, new *DefWithMeta types are introduced that alias the
plain definition types and add extra generic parameters. This way the
only code that needs to deal with the extra metadata parameters is the
compiler code that reads and writes them - the existence of this metadata
is transparent to the runtime, as it should be.

to be honored in backward compatible way between versions. The type of the
return value of `defineInjectable` on the other hand is private and can change
shape drastically between versions without effecting backwards compatibility of
libraries publish to NPM. To our users it is effectively an `OpaqueToken`.

not change the semantics. The semantics will need to be corrected

The Router use the type `Params` for all of:
- position parameters,
- matrix parameters,
- query parameters.
`Params` is defined as follow `type Params = {[key: string]: any}`
Because parameters can either have single or multiple values, the type should
actually be `type Params = {[key: string]: string | string[]}`.
The client code often assumes that parameters have single values, as in the
following exemple:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParams
.map(params => params['session_id'] || 'None');
}
}
```
The problem here is that `params['session_id']` could be `string` or `string[]`
but the error is not caught at build time because of the `any` type.
Fixing the type as describe above would break the build because `sessionId`
would becomes an `Observable<string | string[]>`.
However the client code knows if it expects a single or multiple values. By
using the new `ParamMap` interface the user code can decide when it needs a
single value (calling `ParamMap.get(): string`) or multiple values (calling
`ParamMap.getAll(): string[]`).
The above exemple should be rewritten as:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParamMap
.map(paramMap => paramMap.get('session_id') || 'None');
}
}
```
Added APIs:
- `interface ParamMap`,
- `ActivatedRoute.paramMap: ParamMap`,
- `ActivatedRoute.queryParamMap: ParamMap`,
- `ActivatedRouteSnapshot.paramMap: ParamMap`,
- `ActivatedRouteSnapshot.queryParamMap: ParamMap`,
- `UrlSegment.parameterMap: ParamMap`
E.g. for a component like this:
```
@Component({
template: ‘<ng-content select=“child”></ng-content>’
})
class MyComp {
@Input(‘aInputName’)
aInputProp: string;
@Output(‘aEventName’)
aOuputProp: EventEmitter<any>;
}
```
the `ComponentFactory` will now contain the following:
- `inputs = {aInputProp: ‘aInputName’}`
- `outputs = {aOutputProp: ‘aOutputName’}`
- `ngContentSelectors = [‘child’]`
E.g. for a component like this:
```
@Component({
template: ‘<ng-content select=“child”></ng-content>’
})
class MyComp {
@Input(‘aInputName’)
aInputProp: string;
@Output(‘aEventName’)
aOuputProp: EventEmitter<any>;
}
```
the `ComponentFactory` will now contain the following:
- `inputs = {aInputProp: ‘aInputName’}`
- `outputs = {aOutputProp: ‘aOutputName’}`

- `RouterOutlet.locationInjector`
DEPRECATION:
Use `RouterModule.forRoot(routes, {initialNavigation: 'enabled'})` instead of
`RouterModule.forRoot(routes, {initialNavigtaion: true})`.
Before doing this, move the initialization logic affecting the router
from the bootstrapped component to the boostrapped module.
Similarly, use `RouterModule.forRoot(routes, {initialNavigation: 'disabled'})`
instead of `RouterModule.forRoot(routes, {initialNavigation: false})`.
Deprecated options: 'legacy_enabled', `true` (same as 'legacy_enabled'),
'legacy_disabled', `false` (same as 'legacy_disabled').

Previously, the relative order of the AngularJS compiling/linking operations was
not similar to AngularJS's, resulting in inconsistent behavior for upgraded
components (which made upgrading to Angular less straight forward).
This commit fixes it, by following the compiling/linking process of AngularJS
more closely.
Main differences:
- The components view is already populated when the controller is instantiated
(and subsequent hooks are called).
- The correct DOM content is available when running the `$onChanges`, `$onInit`,
`$doCheck` hooks. Previously, the "content children" were still present, not
the "view children".
- The same for pre-linking.
- The template is compiled in the correct DOM context (e.g. has access to
ancestors). Previously, it was compiled in isolation, inside a dummy element.
For reference, here is the order of operations:
**Before**
1. Compile template
2. Instantiate controller
3. Hook: $onChanges
4. Hook: $onInit
5. Hook: $doCheck
6. Pre-linking
7. Collect content children
8. Insert compiled template
9. Linking
10. Post-linking
11. Hook: $postLink
**After**
1. Collect content children
2. Insert template
3. Compile template
4. Instantiate controller
5. Hook: $onChanges
6. Hook: $onInit
7. Hook: $doCheck
8. Pre-linking
9. Linking
10. Post-linking
11. Hook: $postLink
