context api

Context API

• Use to manage state because it is "global" : Context provides a way to pass data through the component tree without having to pass props down manually at every level

Important Syntax

• const MyContext = React.createContext(defaultValue);
• <MyContext.Provider value={/* some value */}>
• Used inside of classes - static contextType = MyContext;
• Used inside of app.js - `import {ThemeContext, themes} from './theme-context';
• Used inside of app.js import ThemedButton from './themed-button';
