Before you jump to the next framework, make sure it’s needed.
You may learn it, of course! The more you study, the better you work. But you don’t need to ‘upgrade’ all of your Angular apps to Vue2, if your team work with Angular. If you change the technology, you should be able to explain why. If “it’s cooler” is your answer, rethink!
The community around cool stuff tend to have a lot of people who barely use the tool, but advocate it everywhere they can (for the next 2 months, when they will jump to the next trend). They have projects in every other technology on their github, but never the one they defend so much. As I said: Where is the production taking place? There’s no time to produce anything when you spend all of your time being cool.
You should not spend one more second choosing a JS framework. Your app should choose it.
