What is Angular, and how is it different from AngularJS?

Short answer: Angular is a TypeScript-based open-source front-end web application framework developed by Google for building single-page applications (SPAs).

Explain a bit more

Key Differences: Feature AngularJS (v1.x) Angular (2+) Language JavaScript TypeScript Architecture MVC (Model-View-Controller) Component-based Mobile Support No Yes Performance Slower due to two-way binding Faster with unidirectional data flow Dependency Injection Limited Robust and built-in Real-Time

Example code

AngularJS was used in legacy projects (e.g., dashboards in older admin panels). Angular is used in modern SPAs like Google Ads, Gmail, Netflix dashboards, etc.

Real-world example (ShopNest)

A shared CartService is injected into header and product pages so both see the same cart count.

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.
