Created page with "An '''immediately-invoked function expression''' (or '''IIFE''', pronounced "iffy") is a JavaScript design pattern which produces a Scope (computer science)|lexical..."

New page

An '''immediately-invoked function expression''' (or '''IIFE''', pronounced "iffy") is a [[JavaScript]] [[design pattern]] which produces a [[Scope (computer science)|lexical scope]] using JavaScript's [[JavaScript function scope|JavaScript's function scoping]].

== Description ==

Immediately-invoked function expressions can be used to:

* Avoid variable hoisting from within blocks
* Protect against polluting the global environment
* Simultaneously allow public access to methods while retaining privacy for variables defined within the function

This pattern has been referred to as a '''self-executing anonymous function'''; [[Ben Alman]] introduced "IIFE" as a more semantically accurate term for the pattern, shortly after its discussion arose on comp.lang.javascript.
