Implementing Context API for Global State Management in React

React's Context API provides a way to pass data through the component tree without having to pass props down manually at every level.

First, create a context.

import React from 'react'; const MyContext = React.createContext(defaultValue);

Next, provide the context to the components that need it.

<MyContext.Provider value={/* some value */}>

Finally, consume it in your components.

class MyClassComponent extends React.Component { static contextType = MyContext; render() { return <div>{this.context}</div>; // value from MyContext.Provider } }

Or in functional components, use the useContext Hook.

import React, { useContext } from 'react'; const value = useContext(MyContext);

Remember, Context API is designed to share data that can be considered “global” for a tree of React components, like the current authenticated user, theme, or preferred language.
