Well explained Adeel! I have one doubt though. Does this API support group chats? I got this doubt from this function: "subscribeOtherUser(room, otherUserId)". Since here the second arg is an individual user ID and not an array of multiple users who could be a part of a group conversation.

yes the idea is every chat is a group chat, even if it has 2 people in it. It is a group chat.

I just got how absurd my doubt was. But now my doubt is, whenever a client connects to our WebSocket, then as per this: "global.io.on('connection', WebSockets.connection)", the connection method gets invoked. But in the function definition, it requires an argument: "connection(client) { ... }", so during function call why aren't we passing any? I'm just a beginner to node so please bear with me. Another doubt is, in this: "subscribeOtherUser(room, otherUserId)", what is actually "otherUserId"? Please help man.
