Does anyone know/have a script or function to add indentation to javascript code? I've been searching for this on Google for quite some time now, and I can't seem to find anything.

Basically what I need to do is make this, for example:

(function(){(function(){alert('whatever')})()})()

Become:

(function(){
    (function(){
        alert('whatever')
    })()
})()

Thanks in advance :)

How can I automatically format JavaScript properly?

As an example, this:

(function(){(function(){alert('whatever')})()})()

Should become:

(function(){
    (function(){
        alert('whatever')
    })()
})()
