Angular 1 is now up to 1.5.x and still has on going development. I think people have been scared away from learning Angular 1 because of the Angular 2 announcement. I'm trying to remember the details, but I believe support for Angular 1 will continue for a couple more years.
With any luck, Angular 1.x will be like Perl 5.x - still supported about 20 years later :-)
Did I just compare Angular 2 to Perl 6?
Alas, Angular 2 is threatening to actually roll out sooner rather than later.
And you'll get started in no time, no need for nodejs and zillion packages from npm, or even a cli tool and what not.
it's one file you drop into your html page. Vue.js explains clearly how you should build a Vue application and is honest about its potential limitations. There is no surprise nor magics. No IoC container forced on you if you're not into that kind of voodoo.
React is good too, I recommend either of them. I'd have recommended you Angular 1 3 years ago, now I can't, I have no idea if they'll stop developing that version at some point in time.
