Are their alternatives to IRHydra2 that work now (or indeed on different JS engines)? I generally code with an attitude of "a sufficiently-smart-optimizer should understand this", but it's clear that in a lot of cases writing ugly code can be more performant. I would actually be more interested in highlighting opportunities for engine improvement over just making a particular piece of my code faster.
