Personally I see the variety of frameworks as a sign of health not fragility. Vue, eg., spurred React to become much better and less tedious to code. Svelte took nextjs which is commonly used for React and made an even better framework imo, while React keeps improving. You can even mix and match components. Personally I think JS is overall very healthy.

It happened to me too, multiple times. I guess we just need to take it slowly, one thing at the time and not forcing ourselves intowantinfg to learn everything
