How do I use the Context Hook in TypeScript?

To use the Context Hook in TypeScript, you first need to create a context using React.createContext(). Then, you can use the useContext hook to access the context values in your components.

Can you show me a simple example?

Sure! First, create a context: const MyContext = React.createContext<MyContextType | undefined>(undefined);. Then, wrap your component tree with MyContext.Provider and use const value = useContext(MyContext); in your components.

What if I want to provide a default value?

You can provide a default value by passing it as the second argument to createContext. For example: const MyContext = React.createContext<MyContextType>({ defaultValue });.

Is it possible to use multiple contexts?

Yes, you can nest multiple context providers in your component tree to use multiple contexts. Just make sure to use the correct useContext for each one.
