What is the purpose of BrowserModule in Angular?

Short answer: BrowserModule includes services essential for running the app in a browser. It also exports CommonModule. Should only be imported once, in the root AppModule. It sets up things like DOM rendering, sanitization, and event handling.

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

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
