API kontekstowe w React.js

// In App.js 
<NoteState>
	components where you want to use this context which you created    
</NoteState>

// In NoteContext.js 
import { createContext } from "react";

const NoteContext = createContext();

export default NoteContext;

// In NoteState.js or whatever name you want to give
import NoteContext from "./NoteContext";

const NoteState = (props)=>{
  // you can also pass state here also or functions also 
    const user = {
        name: "Gourav Khurana",
        age: 19,
        caast: "General"
    }
    return (
        <NoteContext.Provider value={user}>
            {props.children}
        </NoteContext.Provider>
    )
}
export default NoteState;


This is all about Context API how to create it and add it to Components 

Now how to use it in the Components :- 
  
import React, { useContext } from 'react';
import NoteContext from "../contexts/notes/NoteContext";

const About = () => {
    const contextValue = useContext(NoteContext);
    return (
       you can simply use here. 
    )
}

export default About
