What are the differences between context and props in React?

What are the differences between context and props in React?

In React, props are used to pass data from parent to child components, while context provides a way to share values across the component tree without passing props down manually at every level.

Can you give me an example of when to use context instead of props?

Sure! Use context when you have global data, like user authentication or theme settings, that many components need access to, rather than passing it through every component.

Are there any performance implications when using context?

Yes, using context can lead to performance issues if not managed properly, as it can cause re-renders of all components that consume the context whenever the context value changes.

How do I create a context in React?

You can create a context using React.createContext(), and then use the Provider component to pass the context value to its children.
