CoffeeScript translating to jQuery in JS

I am under the impression that coffeescript translates its code to pure, normal javascript. However, some parts (such as ID selectors), translates in to jQuery ID selectors. This means that I have to link a jQuery script to run this code.

What is the reasoning behind this? Why translate to #(jQuery) ID selector instead of document.getElementByID(normal javascript)?

jQuery is a library written in JavaScript, not a language.

We just use this library with normal JavaScript, and it has nothing to do with Coffeescript.

You're mistaken. ID selectors aren't a part of CoffeeScript syntax, they're a part of jQuery. When you use $('#whatever') in CoffeeScript, you're writing jQuery, not CoffeeScript. CoffeeScript isn't "compiling to jQuery", it's already jQuery.

Additionally, document.getElementById isn't "normal JavaScript". JavaScript is a language, like CoffeeScript is a language. DOM access is an API made available to JavaScript by a browser. Server-side JavaScript, which is every bit as much "normal JavaScript" as in-browser JavaScript, has no such thing as document.
