Question for frontend folks: are you expected to master what to me seems like this endless list of frameworks (js,css and server side), to succeed in your career? Is it accurate to say that entering the field is harder today than it has ever been as a result of framework fragmentation?
Svelte (or Qwik or Solid.js) for example, I personally wouldn't use it in production but it's still nice to learn because it helps me know more about React alternatives.
I'm not sure which type of company uses Vue. Maybe smaller agencies with the option to choose more freely?
Most front end devs, in my experience, want to optimize the developer experience, increase performance, and or reduce boilerplate, so the new fancy framework might show promise in doing said things, and that’s what makes you want that framework to do well.
If a job requires a new framework, it’s likely that the CTO or senior devs of that company believe the above.
