I’ve come to admire the simplicity and style of jquery. There are some cons to it’s approach of using context (as can be seen as this in the for instance “each”):

jQuery("#table tr").each(function(){

This wreaks havoc with some object oriented programming techniques that uses this for the object reference:

function ClassSmurf(){ = "smurfette";
    this.SmurfAround = function(){ alert("Smurf: "; }

This is a simple example broken by jquery’s use of context (that jQuery binds this). There is a simple work around:

function ClassSmurf(){ = "smurfette";
    var that = this;
    this.SmurfAround = function(){ alert("Smurf: "; }

Note that we capture the object instance as a private variable. We do get some additional boilerplate in order to have jQuery safe “classes”. Don’t take me wrong. I love that we have jquery.
