> No, that a switch statement is more verbose than a single function. You're vacillating and applying an inconsistent standard. The switch statement is used where multiple listeners are being attached, therefore it wouldn't work with your "single function". You'd need multiple functions. Give any example passing functions directly as the callback to `addEventListener` to demonstrate your case, please. The equivalent version that simply implements DOMEventListener will be less verbose, be lighter on resources (both with memory use and with runtime), and have no need for any this-binding workaround weirdness.
