re: the why not is easy, cpu time is cheap, developer time isn't. if the optimizations are bad for the readability of the source code and imperceptible...

I think we're discussing the same thing from two different angle, but let's just say if developers take a bit of time upskilling and finding new ways to solve problems more efficient you'll have a performing app and save time finding where to optimise in a large code base.

Back to your point, a developer spending a bit of time reading will help much more than simply code and wait for a bug or a ticket to be raised later on performance.

Last you're just taking one of the points and generalising it, perf tuning is a broad aread, this is one of the thousands

yeah i guess i fall pretty heavily on the side of legibility before everything else. especially in a high-level language like javascript. most of the time, in most cases, you're just not going to need to exploit the weirdness of the language itself for performance tuning. usually what happens is a hot spot is identified some time down the line when something about the app scales.

and in those cases i would rather a past developer had put their time and energy into making sure their intent is clear before getting clever.
