Too Long; Didn't Read
To follow this ReactJS course series you should have some basic knowledge in JavaScript programming language, even better if you know ES6. To create a React project we need to use a text editor or an IDE to open our React project. The most important file here is the "index.js" file, for now we see JSX code (we will see what it is) and remove all in the wrapping divX code. To start our development server with the command "npm start", our browser will open the app for us at localhost:3000.
