Is there a benefit to using a return statement that returns nothing?

Question

I\'m refactoring a large javascript document that I picked up from an open source project. A number of functions use inconsistent return statements. Here\'s a simple examp

What MIGHT be lost here (not direct with your example) is that you can then have a tri-state object:

var myfunc = function(testparam) {
    if (typeof testparam === 'undefined') return;
    if (testparam) {
        return true;
    }
    else {
        return false;
    }
};

var thefirst = myfunc(true)
var thesecond = myfunc(false);
var thelast = myfunc();
alert("type:" + typeof thefirst+" value:"+thefirst);
alert("type:" + typeof thesecond+" value:"+thesecond);  
alert("type:" + typeof thelast+" value:"+thelast); 

these return:

> type:boolean:true 
> type:boolean:false
> type:undefined:undefined

note: null would return false in this example myfunc(null);
