A very basic object which takes an array of functions and calls them in sequence at defined intervals. I don't imagine a lot of other uses for it, but it was used to save time on a repetitive task on a UI where I wanted to post incremental data to a form

functionQueue.js

function functionQueue (aFunctions, nSecondsInterval)
{
	var _queue = [],
	    _arguments = [],
	    i,
	    oSelf = this;

	nSecondsInterval = nSecondsInterval * 1000;

	function curry(fn)
	{
	    var curryArgs = Array.prototype.slice.call(arguments, 1);

	    return function()
	    {
	        var newArgs = Array.prototype.slice.call(arguments, 0),
	        mergedArgs = curryArgs.concat(newArgs);

	        return fn.apply(this, mergedArgs);
	    };
	}

	function queuedFunction(nFunctionIndex, fQueueItem, nDelayMilliseconds)
	{
	    setTimeout(function()
	    {
	        var nNextItem = _queue[nFunctionIndex + 1];

	        fQueueItem.apply(oSelf, _arguments);

	        if (nNextItem)
	        {
	            nNextItem.apply(oSelf, _arguments);
	        }

	    },
	    nDelayMilliseconds);
	}

	for (i = 0; i < aFunctions.length; i++)
	{
	    _queue.push(curry(queuedFunction, i, aFunctions[i], nSecondsInterval));
	}

	this.start = function()
	{
	    _arguments = Array.prototype.slice.call(arguments, 0);
	    _queue[0](_arguments);
	}
}

Example usage

var myQueuedUpFunctions = new functionQueue ([
    function(){console.log('1st function', arguments[0]);},
    function(){console.log('2nd function', arguments[1]);},
    function(){console.log('3rd function', arguments[2]);}
], 1);

myQueuedUpFunctions.start('pimp','my','ride');
