Why have both socket.connected and socket.disconnected?

[ryanwc]

The Socket.IO Javascript client API specifies both socket.connected and socket.disconnected. The docs.

Why? Why not just one or the other? It's confusing. Is there actually some scenario where they are both true or both false (and what does that scenario mean)?

That's a good question, actually... It was added a while back, in socketio/socket.io-client@558f8b2

Is there actually some scenario where they are both true or both false?

No, I don't think this is possible.

Ah, ok, thanks. I am new to Socket.IO as of yesterday and was afraid I was missing something basic; guess not!

At least for me, having both of those is confusing. But maybe other people feel differently and/or some code now depend on both.

Yes, two properties that convey the same information is indeed confusing. I guess we can remove disconnected in the next major version.
