Hi all
Took an in-depth look at the site sample code.
Coding extensively in JavaScript with the Prototype framework, I saw nothing
very new and/or disruptive in Coffee script.
They seem to ignore javascript's automatic coercion feature when they write:
if (typeof elvis !== "undefined" && elvis !== null) {
alert("I knew it!");
}
As JS coerce both undefined and null to false, you can simply write
if (elvis) alert("I knew it!");
Also because you don't need '{}' when 'if' deals with a single instruction.
If you work on web dev, coding in JavaScript gives you access to the FANTASTIC
Firebug tool (Firefox extension by the facebook team) and its VFP-like IDE:
command window, debugger, coverage profiler and more.
I strongly recommend taking a look at Prototype to ease JS dev.; it's quite
different from other JS frameworks like jquery as it not only extends HTML DOM
model, but the JS language itself.
Regarding arrays and more generically enumerable collections, Prototype offers
a bunch of convenient methods such as each(), map(), detect(), invoke(), and
many more. And of course you can chain calls as every method returns the
element it works on:
[1,2,3].each().detect().map().etc.
If anyone needs guidance or advice on JavaScript and/ HTML DOM dev., I'd be
happy to help.
