I'm with you on that one, React is by far the least productive of the lot and every single method it exposes to you has so many damned footguns it's fucking incredible, no wonder most people complain about slow React apps.

But to be fair to React, it's not entirely its fault. What it did when it came out really changed the paradigm for the better, without it we wouldn't have had component-based frameworks like Vue or Svelte today. It's just that, because of being backed by Meta, it has also far outlived its usefulness and has since been far surpassed by other frameworks that learned from its mistakes, but unfortunately for whatever reason no other framework has been able to usurp it. Anecdotally at least, I've noticed that there are some pretty large and important Vue codebases out there which makes me happy, so perhaps the tide will slowly start shifting and we'll start seeing the better frameworks win out at the end of the day.
