Description rickb 2013-10-31 20:52:59 UTC 
In the code below the printIt function is most certainly used however netbeans 7.4 reports it as unused.

(function(){


	doStuff();

	function doStuff()
	{
		var likeCake = printIt.bind(this, " likes cake");
		["mary", "erica", "abigail", "sophie"].forEach(likeCake);
	}


	function printIt(msg, s)
	{
		console.log(s + msg);
	}

})();

It looks like that there are two objects printIt in the model. If we change the source 

(function(){

	doStuff();

	function printIt(msg, s)
	{
		console.log(s + msg);
	}

        function doStuff()
	{
		var likeCake = printIt.bind(this, " likes cake");
		["mary", "erica", "abigail", "sophie"].forEach(likeCake);
	}
})();

that the definition is first and the usage later, then it works. So IMHO the problem is that the function definitions doesn't look for usages before the definition.
