JSX.lol - Does anybody actually like React?
https://jsx.lol/
I made a brief effort to wrap my head around React because I wanted to do something in WordPress and then realized I didn't want to do it THAT badly.
Bsky is coded in React. I was using Gem to write some TM scripts and it kept saying stuff along the lines of "this is React and content may only be there for a brief moment." I finally had to open source, find the div classnames I wanted to target, & spoonfeed them to Gem. I have never seen so many nested divs, each with a dozen classes.
