What are React Hooks and how do they work with Context?

React Hooks are functions that let you use state and other React features without writing a class. They work seamlessly with Context to manage global state.

Can you give me an example of using useContext with useState?

Sure! You can create a Context, then use useContext to access it in a component, while useState manages local state.

What are some common hooks I should know about?

Some common hooks include useState, useEffect, useContext, and useReducer. Each serves different purposes in managing state and side effects.

How do I create a custom hook?

To create a custom hook, define a function that uses built-in hooks and returns values or functions. This allows for reusable logic.

Are there any performance considerations when using hooks?

Yes, be mindful of how often your components re-render. Using memoization techniques like useMemo and useCallback can help optimize performance.
