Do any of these JavaScript frameworks have decent documentation yet? API docs are all well and good, but I'd really like some examples other than to-do applications. All they really need is an equivalent to the Rails guides at http://guides.rubyonrails.org, which are ample.
Frankly I'd take any example application over a to-do app at this point.
As an aside, I've been using Sammy.js (http://sammyjs.org) more than most of these other frameworks lately, as the effort involved is disproportionate to the rewards unless you're building the entire frontend in JavaScript. For any less-than-enormous project, you really don't need all that complexity.
Heard about sammy, but never looked into it until now. It looks really interesting. I've been looking at emberjs for the past couple of days and I do like what I see, but I always felt it was a little too heavy for what I really wanted. I'm just not ready to make my app just an api enpoint...it's just too much abstraction. Regardless, I'll continue to follow emberjs.
