ForerunnerDB is actually very efficient at updating the DOM, only making changes to the parts of the DOM that link to altered sections of an object / document.

Yes much more... it includes views, triggers / change events, transforms, collection joins and the obvious big one - data binding.

This is correct and because we've been using it in production for some time we would definitely say it makes web app development a lot simpler!
