jQuery, MooTools, object inheritance and JSON

I have previously used both MooTools and jQuery as embedded toolkits in projects of mine. I have used MooTools a lot longer than jQuery, but as I have moved more and more towards jQuery, I now only use MooTools for its nice type capabilities.

Class inheritance

However, I have now decided to drop MooTools altogether and focus on exclusively using jQuery. Since this means that I will no longer have access to the MooTools Object class, I instead use the jQuery extend function to create “inheriting” classes.

In jQuery, I handle this as such:

function InheritingClass() {
	$.extend(this, new BaseClass("optional parameters"));

while the MooTools Object class required a syntax like this:

var InheritingClass = Class({
	Extends: BaseClass,
	initialize: function() { this.parent("optional parameters"); }

The MooTools example requires knowledge about the object model, while the jQuery example only requires developers to know about how to use the extend method. The jQuery example feels better.

JSON encoding/decoding

MooTools features a nice JSON parser and serializer, which I will not be able to use anymore. jQuery contains (at least) two functions that can be used to handle JSON - parseJSON and serializeArray. However, the latter only works with DOM elements, so it is not really what I was after.

After some reading, it seems like the official JSON JavaScript implementation is the best around, while a jQuery plugin that I found had quite an extensive issue list. So, although it makes me depend on yet another 3rd part component, I chose this nice little class, which I have used before.

MooTools is hereby completely replaced with jQuery (and the small JSON class).
