React is a free JavaScript library developed by Facebook in 2013 (The web giants spoil us). It is a JavaScript library for building user interfaces.
If I take what they say on the official website: "React makes it painless to create interactive UIs". Creating responsive graphical interfaces is not easy in vanilla javascript. React provides valuable assistance in creating complex graphical interfaces. It allows to create single page app.

The success of React is only growing. Since January 2015, the library has been adopted by several of a large web companies: Netflix, Twitter, WordPress, ...

React has several advantages:

  • The content is referenceable: the code can be generated on the server side!

Why Format React Code?

As with all languages, it is necessary to format its code to make it more understandable. Reading unformatted code can be a real pain sometimes (I have mean colleagues haha...). As soon as we work with several people, it is really necessary.

This tool can troubleshoot. But for a professional project, it is necessary to set up this formatting directly on the workstation.

For now, the available options are really limited (Only one option...). If you think of an interesting option, please indicate it in a comment.
