.mapQuestion

// Using the same data from Mason's bonus HW: https://gist.github.com/masondesu/1eafc9e7dff1ca7666ba
// the following will still return an array like the following: 
[Array[2], Array[2], undefined, undefined, Array[2], Array[2], undefined, undefined, undefined, Array[1], undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, undefined, Array[1], undefined, undefined, undefined, undefined, undefined]


var styleZ = items.map (function (item) {
	if (item.style != null) {
		return item.style
	}
})

found a really janky way to do what I wanted to do

items.reduce (function (set, item) {
    if (item.style) {
        set.push(item.style);
    } return set;
}, []).join();
