Using Hooks

A better way to use contexts is with the useContext Hook! That way, we can use context values like any other value, in a similar way to the useState Hook:

  1. Edit src/Header.js. First, we import the useContext Hook from React, and the ThemeContext object from src/App.js:
import React, { useContext } from 'react'import { ThemeContext } from './App'
  1. Then, we create our Header component, where we now define the useContext Hook:
const Header = ({ text }) => {    const theme = useContext(ThemeContext)
  1. The rest of our component will be the same as before, except that, now, we can simply return our Header component, without using an additional component for the consumer:
    return <h1 style={{ color: theme.primaryColor }}>{text}</h1>
