At a high level, the two blocks of code shown are dramatically different in when and why they execute. They do not serve the same purpose. But they are not exclusive of each other. In fact, you can nest them in to each other if you want – although this can have some odd effects if you’re not careful. jQuery’s “DOMReady” function This is an alias to jQuery’s “DOMReady” function which executes when
Once you’ve read this, read the update which has more detailed information about the module pattern’s performance profile! This is an article on the module pattern for Javascript, and some of its neat properties when used for instances. I’ve been using it recently for projects like mapbox.js, and think it’s a neat way to structure code and avoid some of the less likable parts of the language. For
Content needs to be separated into sections and accessed via a single content area using a flat navigation structure that does not refresh the page when selected. Usage Use when there is limited visual space and content needs to be separated into sections Use when there are between 2 – 9 sections of content that need a flat navigation mode. Use when you need to keep user attention by circumventing
Brian Cray ··· Home > Blog > Javascript > Javascript module pattern: When to use it and why Written by Brian Cray on February 23rd, 2012 There have been a few criticisms of the javascript module pattern, despite its many advantages. Take for example Jonathon Snook's “Why I don't like javascript's module pattern”. While everyone has their own style, my fear is that people, given Snook's demanding p
<p>The module pattern is a common JavaScript coding pattern. It’s generally well understood, but there are a number of advanced uses that have not gotten a lot of attention. In this article, I’ll review the basics and cover some truly remarkable advanced topics, including one which I think is original.</p> <h2 id='the_basics'>The Basics</h2> <p>We’ll start out with a simple overv
This pattern is the same concept as the module pattern in that it focuses on public & private methods. The only difference is that the revealing module pattern was engineered as a way to ensure that all methods and variables are kept private until they are explicitly exposed; usually through an object literal returned by the closure from which it’s defined. Personally, I like this approach for van
In Ruby, modules are often used to mix functionality into concrete classes. Another excellent pattern is to extend objects as a way of avoiding monkey-patching classes you do not “own.” There’s a third pattern that I find handy and expressive: Using modules as object predicates. Let’s begin by defining the problem: Representing object predicates. We have some objects that represent entities of som
Using a number of newer language features in Scala it's possible to implement a composable component system and create components using the so called Cake Pattern, described by Martin Odersky in the paper Scalable Component Abstractions and also in a recent talk. Several of the Scala features used in the Cake Pattern have corresponding Haskell features. For example, Scala implicits correspond to H
One of the shortcomings of JavaScript objects is the lack of support for private members. The ability to create private members makes external APIs more meaningful and helps keep code more manageable and DRY. The Module Pattern, pioneered by Douglas Crockford while building the YUI library, is a mechanism that allows for creating public and private members in JavaScript. This post looks at the pat
Most of my Javascript functions are relatively simple, and called for their sideeffects: I use jQuery to manipulate the DOM or make Ajax-calls. I prefer to write my functions in the "revealing module pattern" style. I just discovered that JSDoc- annotating Javascript files has a benefit: with the help of the annotations, Eclipse's JS Development Tools can parse my JS file and fill the Eclipse Outl
What is Module Pattern? Modules are an integral part of any robust application's architecture and typically help in keeping the units of code for a project both cleanly separated and organized. The module pattern is a common JavaScript coding pattern. To understand Module Pattern you should have knowledge about the Closure principle of JavaScript. What is Closure? Closures are a means through whic
