Angular doesn't do this (batch DOM updates) - but because Angular's $digest cycle is a batch, it's fairly close (or at least, less bad than Backbone's default behaviour).

Dirty checking and watch execution happens in batches, but the resulting DOM updates are executed ad-hoc within each batch iteration - without any regard for requestAnimationFrame or forced synchronous layouts for instance.

(React does too.)

Meteor UI does it as well.

Didn't know about fastdom, thanks for sharing!
