Example text

MyFunction(); //outputs newObject this by default refers to the object a function is contained in. Since myFunction() is a property of the global object, this is a reference to the global object, which is window. Now when we mix myFunction() into a newObject, this now refers to newObject. In PHP and other similar languages, this always refers to the the instance of a class containing the method. You could argue that JavaScript is doing something stupid here, but truthfully much of the power of the JavaScript language comes from this feature.

Com/kriskowal/es5-shim³⁶ Understanding Async One of the things that tripped me up the most when beginning to work with JavaScript code, jQuery in particular is the fact that some operations are asynchronous. There were many times that I wrote code in a procedural manner expecting a result to be returned immediately without realizing it. log(remoteValue); //outputs "false" It took me a while to realize that you need to program around asynchronous calls using callbacks to deal with the outcome of my ajax calls.

Patterns and Code Organization 50 Whenever I find myself building something with a potential for reuse, I break it out into a modulebased jQuery plugin. The best part about this approach is that it forces you to use–and test–the code you write. By using something as you build it, you’ll quickly identify strengths, discover shortcomings, and plan changes. This process leads to battle-tested code ready for open-source contributions, or to be sold and distributed. I’ve released my (mostly) polished plugins as open-source projects on GitHub⁴⁸.
