• React context is a way to manage state globally.

• It can be used together with the useState hook to share state between deeply nested components more easily than with useState alone.

//Pass data from app component to compC ile through file:-
// App->CompA->CompB->CompC
import { createContext } from 'react';

export const NameContext = createContext()

function App(){
    return(
        <div>
            <NameContext.Provider value={'Megha'}>
                <CompA/>
            </NameContext.provider>
        </div>
    )
}

CompC File:- code

import { useContext } from 'react';
import { NameContext } from './App';
function CompP(){
       const myName = useContext(NameContext)
    return(
        <div>
               <h1>{myName}</h1>
        </div>
    )
}

Note:- To do this without cintext, we will need to pass the state as "props" through each each nested componets.this is called "prop drilling".
