Passing arguments in anonymous functions in JavaScript

Question

Sometimes I see JavaScript that is written with an argument provided that already has a set value or is an object with methods. Take this jQuery example for instance:

Here's a example of passing parameters into anonymous function

    var a = 'hello';

    // Crockford
    (function(a){alert(a)}(a));

    // Others
    (function(a){alert(a)})(a);

It uses closure, since it's an anonymous function (it actually all depends how you wrote it)
