I think this comment is a bit out of date, especially if you’ve been watching JS from a distance for the past couple decades. This would’ve been true circa 2014. In 2023 it’s obsolete.

There’s one framework that won, that’s all you have to learn, as far as the industry goes (as opposed to hobbyists) it’s been decided. React won. React is the framework you learn.

“Popular frameworks for the past 6 years” - React has been dominant over that entire time period, from beginning to end. React is what you would’ve reached for 6 years ago (it was already mature then, in 2017) and it’s what you’d turn to now. This is what I mean. You could update your React code to use hooks instead of classes - or you could not, it will continue to work if you don’t.

The “JS changes all the time” take is frankly out of date in 2023. “Which framework do I learn…” you learn React, the framework that won. It’s pretty much that simple.
