问题 Can someone explain me simply the main differences between Operational Transform and CRDT?

I ask this question because I am trying to see how to implement a

I ask this question because I am trying to see how to implement a collaborative editor for HTML documents, and not sure in which direction to look first. I saw the ShareJS
