Creating A Client-Side Shopping Cart

Session storage is a new feature introduced by the W3C’s “Web Storage” specification. It’s supported in Internet Explorer 8+, Firefox, Chrome, Safari and Opera Desktop (for a complete list, please consult “Can I Use”).

var quantity = 2;
var updatedTotal = total * quantity;
sessionStorage.setItem( "total", updatedTotal ); // '240', a string

In this series of articles, we’ll cover in depth a practical implementation of session storage by creating a complete e-commerce shopping cart with the sessionStorage object and jQuery.

Understanding JavaScript’s Function.prototype.bind

Function binding is probably your least concern when beginning with JavaScript, but when you realize that you need a solution to the problem of how to keep the context of this within another function, then you might not realize that what you actually need is Function.prototype.bind().

render: function () {

    this.getAsyncData(function () {

        this.specialFunction();

        this.anotherSpecialFunction();

    }.bind(this));

}

Writing A Better JavaScript Library For The DOM

As developers’ interest in JavaScript increases by the minute, a lot of people are becoming curious about how native APIs really work and about when we can just use them instead of including an extra library. Lately, I have started to see more and more problems with jQuery, at least my use of it.
