I worked as a React developer (among other things) for several years at Dropbox and came away thinking that React is great and the only way to make progress is to lean into it further.
Although I came away with little good to say about how Dropbox and publicly-traded companies in general are run.
Also programming just sucks. The fact that it sucks is one of the reasons I focus on math instead. My brain, which needs everything to make sense, just can’t handle the misery of writing code.
Although occasionally I write a bit of code anyway.
I have occasionally written references for myself.
