IIFE (v4)

Description

Immediately-Invoked Function Expression (IIFE)

http://benalman.com/news/2010/11/immediately-invoked-function-expression/

Note that it´s only with Crockford and dogballs you can define what should be returned from the IIFE.

  • void will always return undefined.
  • new will always return object.
  • bang will always return false.

Tilde is a different beast all in it´s own.

It´s recommended to go with either Crockford or dogballs as they are the most portable and conventional.

var foo = 'foo';
