Summary
In this chapter, you learned how to use different flavors of JavaScript with Node.js. You have seen how Babel can be installed, configured, and used to transpile your code to the JavaScript standard supported by the target version of Node.js.
Right now, you should also know the basics of the most important JavaScript flavors: Flow and TypeScript. We discussed how they can be installed and configured. Of course, to practically use these flavors, you’ll need additional material to learn their syntax and master the concepts behind these languages. A good book to learn TypeScript is Mastering TypeScript by Nathan Rozentals.
In the next chapter, we will discuss a quite important area of tooling – applications that can give our code improved consistency and validation.
