Coffeescript is a little language that compiles into javascript. underneath all of those embarrassing braces and semicolons, javascript has always had a gorgeous object model at its heart. coffeescript is an attempt to expose the good parts of javascript in a simple way.
the golden rule of coffeescript is: "it's just javascript". the code compiles one-to-one into the equivalent js, and there is no interpretation at runtime. you can use any existing javascript library seamlessly (and vice-versa). the compiled output is readable and pretty-printed, passes through javascript lint without warnings, will work in every javascript implementation, and tends to run as fast or faster than the equivalent handwritten javascript.
this package contains a concatenated and compressed version of the coffeescript compiler. to use it in the browser, include the script after any inline script tags of type "text/coffeescript" on the page. it will compile and evaluate all of the scripts in order.
