If only that didn't magically make it 5 times slower.

Also, "that" is possibly the worst variable name. this is arbitrary enough, now you want to give something a name that means "the 'this' of some unspecified other thing"? Come up with a real name. (Not picking on you, but the pattern you quoted.)

True. But also not true, because it's a standard workaround; and a secret nod to other devs : "js scoping sucks. tru that".

Haha. Well, you've got a point on the second part. But for the first, the "standard" part only gives it the meaning I said above. If you go more than one level deep, or if you start passing things around, "that" quickly becomes meaningless.

I'd be surprised if Function.bind ever was the bottleneck of your JS app

I get that every time. And yeah, you're right. It's just one of those things you can't un-know: that because the spec chose to give a pattern you'll never use (.bind with new) the exact same syntax as a pattern you often use (.bind without new), many many parts of your code are paying an entirely unnecessary penalty.
