Just like that former frontend dev in 2016 who switched to backend, I did the same exact that year, after meeting with React & Angular. ...Although, the rationale for React (hashing and re-rendering data tree only partially) seemed very compelling. I also remember the 2009 Crockford's lectures on Javascript where he insisted that JS was getting faster with JIT, and all the devs needed to do was to make functions return quickly and postpone the rest of the work to the async event loop. Turned out, that expectation of high performance from JS was just an optimistic extrapolation of Google Chrome's JS optimizations. They happened in 2007-08 and probably ended in 2009 when the lectures were given.
