@_luna jQuery _was_ absolutely awesome! So much so that its best features have become part of the standard.
jQuery's selector syntax has become part of JavaScript; $() became querySelector() and querySelectorAll().
jQuery's animation capabilities have become part of CSS as animation with keyframes and transitions.
I don't think there's actually anything today that takes the same approach as jQuery did during the height of its popularity and that's because standard JS has become so good.
"The framework of the week" is a running joke among JS nerds. There are so many and, the thing is, they're all good.
I can't recommend one. I don't know enough, but I can tell you that I've used both React and Vue professionally and I really enjoyed working with them.
If you're planning a career in Web Development, I _think_ you'll still find React in more job ads, but that depends on a lot of factors.
