1. What is Angular and how is it different from React?

Business Use Case: “Our company is deciding on a frontend technology for a new provider portal. As a backend developer, what’s the key difference you see between Angular and React?”

Answer: Angular is a comprehensive, opinionated framework for building web applications, developed by Google. The key difference is that Angular provides a full suite of tools out-of-the-box (like routing, state management, and HTTP client), while React is a library focused only on the UI, requiring you to choose other libraries for routing and state management. Angular uses TypeScript by default and updates the real DOM, whereas React uses a Virtual DOM.
