Question

Context

I’m attempting to build a basic pong multiplayer webapp based around javascript/jquery. I thought about how I could synchronize movement between the players on both clients and decided that I wanted to keep it as much client-side as possible. Played around with some ideas, (it was as bad as me thinking about using txt files with 3 boolean values and a user id being called for every single game) but I really couldn’t think of any better way short of using some kind of js backend engine. (which i really do not want to do).

Example of using WebSocket in multiplayer games:
