Does Coffee Script allow using Javascript libraries?

Question

It looks like Google's Dart language doesn't allow you to call native js functions (say, using jQuery or my existing .js code).

Does CoffeeScript allow any of the above?

Answer 1

yes you can use any javascript library with coffescript, just include the lib the usual way and write your code in the coffeescript 'style', so for a jquery example:

$(function () {
    $('.something').on('click', function () {
        console.log('you clicked me');
    });
});

becomes

$ ->
    $(".button").on "click", ->
        console.log('you clicked me');

A quick google found some ineresting blog's on the subject, coffeescript & jquery fun and using jquery with coffeescript.

There is also a pragmantic programmer book with a chapter focused on using jquery and backbone in coffeescript applications

n.b. as pointed out, remember that the coffeescript 'compiler' wont check that functions exist, only that the syntax is correct
