Re: why not MediaQueryList.onchange

Hi

What I meant was a resize event per MediaQueryList, if you look at www.simplestatemanager.com you would see that it allows your to have a enter, leave and resize event. 

So if we think of this in terms of the MediaQueryList, we currently have

var mql = window.matchMedia("screen and (max-width:768px)");
mql.addListener(function(e){
    if(e.matches){
        console.log(‘matched');
    }
    else{
        console.log(‘unmatched');
    }
});

But what we might have instead is:

var mql = window.matchMedia("screen and (max-width:768px)”);

mql.addEventListener(“match”, function(){
	console.log(‘ive matched’);
});

mql.addEventListener(“unmatch”, function(){
	console.log(‘ive unmatched’);
});

mql.addEventListener(“resize”, function(){
	console.log(‘while matched and browser is resized I will fire’);
});

So this gives us the ability to add a resize event specific to a “state” i.e. while the media query matches.
