How do you add third-party libraries using Angular CLI?

Short answer: Use npm or yarn to install the package: npm install lodash If the library requires it, add typings: npm install --save-dev @types/lodash Some libraries have Angular-specific schematics that you can add via: ng add @angular/material This command installs and configures Angular Material automatically.

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.
