How do you enable AOT (Ahead-of-Time) compilation in Angular?

Short answer: AOT compiles templates before runtime, improving startup performance. Enable via: ng build --aot Usually enabled automatically with --prod. Can be configured in angular.json: "configurations": { "production": { "aot": true }

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.
