Code Review
This pull request introduces a caching mechanism for the TypeScript configuration in the Angular build process to improve performance during watch mode rebuilds. The reviewer suggests enhancing this cache by tracking the 'rootFiles' to ensure the cache is properly invalidated when the set of root files changes, preventing potential compilation errors or stale configurations. All review comments are actionable and provide necessary improvements to the implementation.

…tion Reusing TypeScript's extendedConfigCache across watch rebuilds eliminates redundant reading and re-parsing of extended tsconfig files from disk. The referenced configuration files are also tracked so that entries in the cache are invalidated when those files change on disk. See: angular/angular#71034
