Sure! Here is an example of how you can use the useContext hook in a React component with TypeScript:

import React, { useContext } from 'react';

// First, we need to create a context
export const MyContext = React.createContext<MyContextType | undefined>(undefined);

// Then, we can define the type for the context value
type MyContextType = {
  someValue: string;
  someFunction: () => void;
};

// Now we can use the context in a functional component like this:
function MyComponent() {
  // useContext accepts a context object (the value returned from React.createContext)
  // and returns the current context value, which is determined by the nearest 
  // <MyContext.Provider> above the component in the tree
  const context = useContext(MyContext);

  // Now we can use the context value in our component
  return (
    <div>
      {context.someValue}
      <button onClick={context.someFunction}>Click me</button>
    </div>
  );
}

// To provide a context value for a tree of components, we can use a context provider:
function App() {
  return (
    <MyContext.Provider
      value={{
        someValue: 'Hello, world!',
        someFunction: () => console.log('Button was clicked'),
      }}
    >
      {/* The context value will be available to all components below this provider in the tree */}
      <MyComponent />
    </MyContext.Provider>
  );
}

I hope this helps! Let me know if you have any questions.
