JavaScript is a great language, very easy to learn ad use on a daily basis.

But by itself it lacks a few features that would make programmers' lives a lot easier.

The first thing is the beloved fetch function that's available to JavaScript when running inside a browser, like Chrome or FireFox. Since our environment is not a browser, we had to bake the fetch function into our aftJS language ourselves, and we did.

Another well-known and loved JavaScript library that's used by tons of programmers is Underscore.js so we added that one in as well.
