Yeah, I think I sometimes weave back-and-forth. I try to avoid thinking about "micro-optimizations", but can't help myself. As I'm writing this series I'm compiling together a small and opinionated library that uses a lot of these concepts, and I am tending to use native methods, for loops, while loops etc. in favor of performance....

but I should probably stop that and instead favor the clean code following the very principles they are there to promote! One of my points was that performance doesn't really matter here anyway.

Thanks for pointing out. I might update a couple spots.
