I never "learned" react because the "create react app" would literally never install for me in the early days. There were literally so many dependencies I never got it to build as a novice, I tried svelte everything worked and I got to spend that time building.

I can only speak for Svelte, in Svelte 3/4 it was so dead simple that I built my first basic webapp with 0 javascript, css or html experience in 3 days.

By week 2 I was trying out different UI libraries and css frameworks, that part was super rough though, back then lots of compat issues.
