> const performs a lot better in optimized code than var or let
This puzzles me; if only ever one value is assigned, I would have expected at least let to perform identically to const in optimised code, because I expect the optimiser to look at the let and say “never reassigned, turn it into a const”. By the sound of it, I’m wrong, and I’d be interested to know why I’m wrong.
