Technical requirements for this section
  To follow along with the project in this section all you need is:
  
    - A computer running Windows, Mac, or Linux.
 
    - A modern web browser. The latest version of Google Chrome is recommended, since I'll use its Developer Tools in the videos.
 
    - Your favourite text editor or IDE. I use  Visual Studio Code in the videos; it's free and open source, and works on Windows, Mac, and Linux.
