ReactJS useContext Hook

useContext() Hook

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

• Step 1: Create Context Component
  eg:
  // MyContext.jsx
  import React,{ createContext } from “react”
  const MyContext = createContext();

  export default MyContext;

• Step 1: Using Context Provider

eg:
// App.js
import React from 'react';
import MyContext from './MyContext';
import ChildComponent from './ChildComponent';

function App() {
const contextValue = {
name: 'John',
age: 30, };

return (





);
}

export default App;

• Step 3: Using useContext hook eg:

// ChildComponent.js

import React, { useContext } from 'react';
import MyContext from './MyContext';

function ChildComponent() {
const context = useContext(MyContext);

return (

Name: {context.name}

Age: {context.age}

);
}
export default ChildComponent;
