JS is not "yesterday's option", quite the contrary. The same for HTML and CSS. If you want to be proficient fast, you should focus on a good foundation on all three.

But if you are past that, I would suggest Vue. I have not used it myself, but lots of colleagues tell wonders about how easy, comfortable and fast it is to built things on it.

There are doubts about it being production-ready for larger companies and projects, but it seems to be the king of productivity nowadays.
