Non-Angular frameworks and dirty checking

[sllvn]

Do other frameworks use dirty checking? Answer: yes (React,Ember,Polymer)

AFAIK, this is false or misleading at best. Ember uses accessors to provide model updates to its bindings. React uses the virtual DOM and a diffing algorithm to provide updates. I don't know enough about Polymer to make a claim.

Thanks for submitting an issue. You're right about Ember they were planning on using Object.observe which would mean they would be using dirty checking I did the same mix up with di and added Polymer by accident. (Ember has been removed )

React uses dirty checking. They're just better at it compared to ng1 since they prune the tree and other ways to optimize (immutable data contract [knowing the data is immutable you can depend on it's references]) the tree before running their “diff-ing” (dirty) algorithm. Both frameworks took the idea from game development. Facebook is pretty good at marketing so another example being Flux(really just pub/sub architecture on the client)

Polymer on the other hand uses dirty checking when you don't have Object.observe
