What is the significance of the React context API?

The React Context API provides a way to share values between components without having to pass props through every level of the component tree.

This is particularly useful for global data such as themes or user authentication. You create a context, provide a value, and consume it in any component that needs it.

Here’s how to implement it:

import React, { createContext, useContext } from 'react';

const ThemeContext = createContext();

const App = () => (
  
    
  
);

const Toolbar = () => {
  const theme = useContext(ThemeContext);
  return 
Toolbar
;
};
