If you’re working with a legacy React codebase, then this course will prove useful. React has seen a great deal of change over the years, but there might be situations where you have to work with an older version.

In this course, you will learn the fundamentals of V15 React. You will learn how to work with an API, how to organize and test your code as well as how to give your React app state. Throughout this course, you will have hands-on experience building a fully functional Hacker News App. By the end of this course, you will be prepared to build your own applications and have something to showcase in your portfolio.

This is one of the most well-written & informative coding books I’ve ever worked through. A solid React & ES6 introduction.

The Road to Learn React by Robin Wieruch is such an awesome book! Most of what I learned about React and even ES6 was through it!

I recommend this to any student or professional interested in learning react basics to advanced level. I have 17 years of experience in web and desktop app development, and before reading this I was having trouble in learning react. It works like magic.

# What is the create-react-app?
The Create React App is a tool built by developers at Facebook to help you build React applications. It does not require any time-consuming setup and configuration. You simply run one command and the create react app sets up the tools you need to start your React project. The rest of the course will loosely follow the file structure followed in the create-react-app. You can learn how to set it up in our [zero configuration lesson](https://www.educative.io/courses/road-to-react-with-class-components/zero-configuration-setup).

# A high-level explanation of the create-react-app
You can see the create-react-app below. I won't explain the specifics of it yet, but you should be familiar with the directory structure below. Essentially, everything starts with the `index.js` file. It imports react, [the react DOM](https://www.educative.io/collection/page/10370001/5687272380825600/5700735861784576) (don't worry if you don't know what that is yet), the app's code itself which is in `App.js` and `index.css` for styling. It then 'renders' (prints/displays) the app on lines 7-10. Notice the tag `<App />` on line 8. This line actually renders the app. The app is defined as a class or 'component' (these will be explained in depth later) in the `App.js` file. 

This lesson gives a brief overview of the create-react-app.
