Don't compare two arrays with ===

So, if you want to check if two arrays are equal, you might want

([] ===
	[][
		// or

		(1, 2, 3)
	]) ===
	[1, 2, 3];

Well, by that you would probably assume two trues come back, but actually, you are going to get false and false.

so, better use join() so you can compare strings.
