This allows the programmer to write code as if the entire page is rendered on each change, while the React libraries only render subcomponents that actually change. Create React App uses Babel and Webpack to transpile and bundle your code (in short, to make it possible to run in the browser). There are rules of hooks[18] which describe the characteristic code pattern that hooks rely on. React does not attempt to provide a complete "application library".
