With TypeScript isolatedModules support, Angular has achieved production build time improvements of up to 10%, significantly enhancing performance for developers.
Enabling isolatedModules ensures TypeScript code is transpiled efficiently by the bundler, which can optimize constructs like enums and eliminate Babel passes for TypeScript.
To activate isolatedModules, update your tsconfig.json with "isolatedModules": true. Ensure that the useDefineForClassFields option is appropriately set for optimal output.
This new feature allows developers to leverage enhanced build speeds while simplifying the transpilation process by eliminating type-checker dependencies.
