> If you want something that keeps the HTML and JS separate ...

I guess my JS knowledge is small enough that I just expect the HTML and JS to be primarily separated. (It seems like a best practice to me, but I haven't experimented with code that wasn't primarily separated, so I'm sure I'm missing some important insights).

Thank you for making the knockoutjs.com recommendation. For someone, with primarily Angular experience, who is looking to broaden their horizon, which of the three would you recommend as the next framework to learn: React, Riot, or Knockout?
