What are the best practices for using the useContext hook in React?

When using the useContext hook, it's important to keep your context values minimal and avoid unnecessary re-renders. You should also consider creating separate contexts for different parts of your application to improve performance.

Can you explain why minimizing context values is important?

Minimizing context values helps prevent components that consume the context from re-rendering when unrelated values change. This leads to better performance and a smoother user experience.

What are some common mistakes to avoid with useContext?

Common mistakes include placing too much data in a single context, not memoizing context values, and using context for state that doesn't need to be global.

How can I test components that use the useContext hook?

You can test components using the useContext hook by wrapping them in a context provider in your tests, allowing you to pass in the necessary context values.
