Closures are an important concept in JavaScript and give raise to some of the real power of the language. Later in this series I will discuss JavaScript module patterns – all of which rely on closures. In order to understand closures lets look at a specific example function.
Browser based JavaScript code is all about manipulating the browser’s DOM.
Up until a few years ago, at DNN Corp we had primarily been using jQuery to do that manipulation. Don’t get me wrong jQuery is an awesome framework, but jQuery directly manipulates the DOM - there is no concept of working with models/objects in jQuery – i.e. separating your presentation aspects from your other logic.
