The Module pattern is based in part on object literals and so it makes sense to refresh our knowledge of them first. Names inside the object may be either strings or identifiers that are followed by a colon.

Outside of an object, new members may be added to it using assignment as follows myModule. Where in the world is Paul Irish today?

That said, if we're opting for this technique, we may be equally as interested in the Module pattern. It still uses object literals but only as the return value from a scoping function.

The Module Pattern The Module pattern was originally defined as a way to provide both private and public encapsulation for classes in conventional software engineering.

What this results in is a reduction in the likelihood of our function names conflicting with other functions defined in additional scripts on the page. Privacy The Module pattern encapsulates "privacy", state and organization using closures.

It provides a way of wrapping a mix of public and private methods and variables, protecting pieces from leaking into the global scope and accidentally colliding with another developer's interface.

With this pattern, only a public API is returned, keeping everything else within the closure private. This gives us a clean solution for shielding logic doing the heavy lifting whilst only exposing an interface we wish other parts of our application to use.

The pattern utilizes an immediately-invoked function expression IIFE - see the section on namespacing patterns for more on this where an object is returned.

It should be noted that there isn't really an explicitly true sense of "privacy" inside JavaScript because unlike some traditional languages, it doesn't have access modifiers. Variables can't technically be declared as being public nor private and so we use function scope to simulate this concept.

Within the Module pattern, variables or methods declared are only available inside the module itself thanks to closure. Variables or methods defined within the returning object however are available to everyone. History From a historical perspective, the Module pattern was originally developed by a number of people including Richard Cornford in It was later popularized by Douglas Crockford in his lectures.

Another piece of trivia is that if you've ever played with Yahoo's YUI library, some of its features may appear quite familiar and the reason for this is that the Module pattern was a strong influence for YUI when creating their components.

Examples Let's begin looking at an implementation of the Module pattern by creating a module which is self-contained. The counter variable is actually fully shielded from our global scope so it acts just like a private variable would - its existence is limited to within the module's closure so that the only code able to access its scope are our two functions.How cute!!!

I found this pattern the other day, and just finished making a pair of these to go along with the dress I made. I actually just used regular fabric, though, and did a casing around the legs as well.

A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh and is not meant to be taken seriously.

It takes the form of a story, usually with dialogue, and ends in a punch is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning.
