What are the main features of Angular 9 and later versions?

Short answer: Angular 9: Default usage of Ivy compiler and renderer.

Explain a bit more

Improved type checking in templates. Better build errors and debugging. Smaller bundle sizes. Later versions added: Strict typing for reactive forms. Improved Component harnesses for testing. Enhanced internationalization (i18n) support. Optional chaining and other TypeScript improvements. Standalone components (Angular 14+), simplifying module-less apps. Signals (Angular 16+) for reactive primitives.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
