3 Simple Things to Make Your jQuery Code Awesome

jQuery is one of the most popular (if not the most) JavaScript libraries in existence and a great number of people use it to do some amazing things. Personally, jQuery is what got me excited for learning JavaScript. The problem is that a lot of programmers don’t understand that with all that power massive amounts of CPU cycles are used. As much as jQuery engineers try to optimize jQuery, they are always limited in how fast they can make it go. There are a few things that you, as a user of jQuery, can do to make your jQuery code faster.

JavaScript Mixins for Functional Inheritance

Mixins are a way to add the functionality of 1 or more objects to a new object, essentially creating a non-standard means of inheritance.

We’ve made it to the final installment in the JavaScript Design Patterns series. That’s right, after this you’ll no longer have any clue what post will be coming out every Monday! Well today, we’ll be talking about the Chain of Responsibility Pattern. This pattern decouples the sender and receiver of a request. This is done with a chain of objects, each of which can handle the request itself or pass it on to the next object. Confused? Read on.

JavaScript Design Patterns: Command

The Command Pattern is a strange beast in the context of object-oriented programming. Unlike most objects, a command object represents a verb, rather than a noun. This is a little less odd in a language like JavaScript where functions are actually a type of object, but the classical sense of the Command pattern is still different than a function.

It’s just a giant mess of quotes and plus signs.
