IIFE Variations (JavaScript)

iife.js

// from: http://jsfiddle.net/SubtleGradient/Qfawx/
// copied here only because "gists" are slightly easier for me to read

// classic (oldschool)
(function(){/*IIFE*/})();

// new standard
(function(){/*IIFE*/}());

// lol, square
[function(){/*IIFE*/}()];

// fixed for ASI edge-case
;(function(){/*IIFE*/})();
;(function(){/*IIFE*/}());
;[function(){/*IIFE*/}()];


// Force function to be an expression by setting a var to its result
var stuff = function(){/*IIFE*/}()

// ... this is much more obvious. The extra () makes it obvious that it's not a normal function
var stuff = (function(){/*IIFE*/}())

// without the () it's not obvious that it's an IIFE until you read to the end of the last }, That's annoying!
var doStuff = function(){/*normal function*/}


// Force function to be an expression using an operator
// Don't do this, it's silly and too many characters
"" + function(){/*IIFE*/}()
7 && function(){/*IIFE*/}()
0 || function(){/*IIFE*/}()
7, function(){/*IIFE*/}()


// Minimal
// unconventional and confusing to teh n00bz :(
// pretty hawt though, amirite?
!function(){/*IIFE*/}()
-function(){/*IIFE*/}()
+function(){/*IIFE*/}()

typeof function(){/IIFE/}()

~function(){/IIFE/}()
