What are some advanced concepts in Angular and React?
In Angular, advanced concepts include Dependency Injection, RxJS for reactive programming, and NgRx for state management. In React, you might explore Hooks, Context API, and performance optimization techniques.
Can you explain how RxJS works in Angular?
RxJS is a library for reactive programming using Observables. In Angular, it allows you to handle asynchronous data streams, making it easier to manage events, HTTP requests, and more.
What are React Hooks and why are they important?
React Hooks are functions that let you use state and other React features without writing a class. They simplify component logic and promote code reuse.
How does state management differ between Angular and React?
Angular uses services and NgRx for state management, while React often uses Context API or libraries like Redux. Angular's approach is more structured, while React offers flexibility.
Can you give examples of performance optimization in React?
Sure! Common optimizations include using React.memo to prevent unnecessary re-renders, lazy loading components, and using the useCallback and useMemo hooks to memoize functions and values.
