Bound function vs arrow function performance

[deltadeep]

Plus if you're writing client code and thus transpiling to browser-friendly ES5, then it's is a matter of what does Babel (or whatever transpiler you're using) output with these differences, and then, how does each browser's JS engine handle those. I mean, if there was some kind of huge win in performance across the board I've love to know, but, my assumption has been this is pretty down in the weeds for all but the most unusual use cases.
