Angular 2, 4, 5 - too divided and changeable for a stable decision

[Admin]

When I wanted to learn to code with Angular JS I saw that Google team has in development Angular 2.
Well, I said myself to wait a little longer till Angular 2 will be a stable version and with some more documentation with JavaScript.
Now, when I looked for documentation to start playing with Angular 2 JavaScript i saw that Google team has released Angular 4 (in 23 March 2012).
What should I do now, waiting again a little time till they will publish documentation and code examples for Angular 4?
But they already have plans for Angular 5 and 6. So, this changeable, unstable and too divided project helped me to decide myself.
I leave aside the thoughts about Angular and I look ahead towards something stable; new or something I already know.
