How to use context API and Redux in React?

Comment

// 1. Create a new context
const MyContext = React.createContext();

// 2. Define a provider component
function MyProvider({ children }) {
  // 3. Define state and functions
  const [count, setCount] = React.useState(0);

  // 4. Pass state and functions as value prop
  const contextValue = { count, setCount };

  return (
    <MyContext.Provider value={contextValue}>
      {children}
    </MyContext.Provider>
  );
}

// 5. Wrap components with the provider
function App() {
  return (
    <MyProvider>
      <ChildComponent />
    </MyProvider>
  );
}

// 6. Use the context in consumer components
function ChildComponent() {
  const { count, setCount } = React.useContext(MyContext);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
}
