In plain words
This is a JavaScript/Flow implementation of operational transforms for real-time collaborative editing. Built by Kenrick Rilee, it demonstrates the core technology used in Google Docs to enable multiple users to edit simultaneously. The project explores OT's capabilities while acknowledging its complexity, prompting consideration of alternative approaches like CRDTs and WOOT for broader applications beyond text editing.

From the sources
Implementing realtime collaborative editing with operational transforms (OT) was fun. However, the difficulty of the solution is pushing me towards learning about alternate solutions like CRDTs and WOOT. I'm excited about applying realtime collaboration to domains other than text, so the relative complexity of OT is a serious detractor. Operational transform (OT) is one of the core technologies enabling realtime collaborative text editing in Google Docs. It is the most well-known and implemented solution for realtime collaboration. In addition to enabling smooth real-time interaction, OT makes it possible for apps to seamlessly operate in high-latency or even offline situations. Actions…from cricklet.github.io
