How do I manage state in React and Angular applications?

In React, you can use hooks like useState and useReducer for state management. In Angular, services and RxJS are commonly used.

Can you explain how useReducer works in React?

Sure! useReducer is a hook that allows you to manage complex state logic in React. It takes a reducer function and an initial state, returning the current state and a dispatch function.

What about state management libraries? Are they necessary?

State management libraries like Redux for React or NgRx for Angular can be helpful for larger applications, but they're not always necessary for smaller projects.

How do I choose between using a library or built-in state management?

Consider the complexity of your application. If you have simple state needs, built-in options may suffice. For larger apps, a library can provide better structure.
