The seventh part of the course touches on several different themes. First, we'll get familiar with React router. React router helps us divide the application into different views that are shown based on the URL in the browser's address bar. After this, we'll look at a few more ways to add CSS styles to React applications. During the entire course, we've used create-react-app to generate the body of our applications. This time, we'll take a look under the hood: we'll learn how Webpack works and how we can use it to configure the application ourselves. We shall also have a look at hook functions and how to define a custom hook.
