> Sure, I'm working with Angular now. I might switch to Vue.js because I'm not crazy about Angular and I've heard very good things about Vue, but I'm also wondering if I'd like Angular more once I reached proficiency in it.

I am probably preaching to the choir here, but if you are looking to sharpen your skills, it's almost always better to stick with a single tech and learn it really, really well. That doesn't mean it's harmful to step through some Vue tutorials to get a feel for how it is different, however, if you're not careful you can end up losing a ton of time learning about the JS framework du jour and not actually making progress on anything. Especially if you are not in any hurry to build something useful.

Just about the only constant in JS frameworks is that any decision you make now on which one to use will probably be wrong in a year.

That's not to say optimizing for development speed isn't a good thing, especially if you are looking to bang out POCs as quickly as possible to vet startup ideas. But if you're not careful this can devolve into "funtime with tech" that could be a major distraction which might not even look or feel like one.

Speaking from experience :-)
