There is no standard for library authors to ship their library in different ES versions, which can result in vendor libraries to ship ES features which are not supported by one or more browsers that the user's application supports.
With this change, we will be downlevelling libraries based on the list of supported browsers which is configured in the browserslist configuration. Previously, we only downlevelled libraries when targeting ES5.
The TypeScript target option will not effect how the libraries get downlevelled.
Closes#23126
When running protractor, previously we didn't close the dev-server correctly when there was an error which caused the process to keep running following https://github.com/angular/angular-cli/pull/23166
This can be useful to debug slow builds.

Paths within the `angular.json` file should be relative to the location of the `angular.json` file.
The `ngswConfigPath` option was incorrectly using the current working directory for a base path when
a relative configuration path was specified. Most of the time this would work as a build command usually
is executed from the root of the workspace. However, this may not always be the case and for those cases
the actual workspace root is now used to resolve the full path for the service worker configuration file.
An experimental browser application builder (`browser-esbuild`) has been introduced that leverages esbuild as the bundler.
This new builder is compatible with options of the current browser application builder (`browser`) and can be enabled
for experimentation purposes by replacing the `builder` field of `@angular-devkit/build-angular:browser` from an existing
project to `@angular-devkit/build-angular:browser-esbuild`. The builder will generate an ESM-based application and
provides support for ES2015+ compatible output with ES2020 as the default.
This builder is considered experimental and is not recommended for production applications.
Currently not all `browser` builder options and capabilities are supported with this experimental builder.
Additional support for these options may be added in the future.
The following options and capabilities are not currently supported:
* Stylesheet Preprocessors (only CSS styles are supported)
* Angular JIT mode (only AOT is supported)
* Localization [`localize`]
* Watch and dev-server modes [`watch`, `poll`, etc.]
* File replacements [`fileReplacements`]
* License text extraction [`extractLicenses`]
* Bundle budgets [`budgets`]
* Global scripts [`scripts`]
* Build stats JSON output [`statsJson`]
* Deploy URL [`deployURL`]
* CommonJS module warnings (no warnings will be generated for CommonJS package usage)
* Web Workers
* Service workers [`serviceWorker`, `ngswConfigPath`]
The `glob`-based check when adding the sourcemap support packages to the karma setup was incorrectly
skipping the files due to Windows pathing issues. The `glob`-based check, however, is unneeded due
to the already present `require.resolve` checks for the sourcemap support packages which will
throw if the packages are not present.
During the build initialization phase, many paths are converted back and forth between multiple normalized forms. These conversions involve potentially expensive string operations. The majority of the custom path `normalize` function from `@angular-devkit/core` usages have now been removed in favor of the Node.js builtin path functions. This change reduces the need to perform additional string manipulation where possible.
Without the `node_modules` prefix, projects named the same as the excluded package names ex: `webpack` will not compile successfully as all files under the mentioned project will be excluded from being requested by the respective loaders.
Closes#22902
These changes include fixes to tests, timeout and stop of architect to make tests work with Jasmine 4.
One noticeable change that when we didn't stop architect through `run.stop()` this causes Bazel to timeout now.

With this change we replace the custom dimension 8 `AOT Enabled`, with `Angular CLI Major Version`. The motivation behind replacing this dimension is that the there is already an `aot` dimension with id 13 which serves for the same purpose.
More information to why we need a new dimension for the Angular CLI major version can be found #22130Closes#22130
Since Angular 8, the CLI has transformed decorator metadata to a form that can be used by the Angular dependency injector without the TDZ limitations of Typescript's decorator metadata emit feature.
As a result, a JIT application compiled with the CLI no longer requires the reflect metadata polyfill that was provided by `core-js`.
This polyfill was also the last remaining usage of the `core-js` package within `@angular-devkit/build-angular` which allows the `core-js` package to also be removed.

BREAKING CHANGE: Reflect metadata polyfill is no longer automatically provided in JIT mode
Reflect metadata support is not required by Angular in JIT applications compiled by the CLI.
Applications built in AOT mode did not and will continue to not provide the polyfill.
For the majority of applications, the reflect metadata polyfill removal should have no effect.
However, if an application uses JIT mode and also uses the previously polyfilled reflect metadata JavaScript APIs, the polyfill will need to be manually added to the application after updating.
To replicate the previous behavior, the `core-js` package should be manually installed and the `import 'core-js/proposals/reflect-metadata';` statement should be added to the application's `polyfills.ts` file.
`inquirer` has a number of depedencies which slow down module resolution when importing (~138ms) by lazy loading this module we remove this overhead when prompts are not needed.
