[API] Expose 'connected' and 'authenticated' status

[haganbmj]

Is this a request for a new feature or a bug report?
Enhancement

General Description:

• Expand the ._connected variable to either a combined state object or just add an ._authenticated variable.
• Consider dropped the underscore as these are intended to be publicly visible.

yes pls.
problem still exists.
i have to use protected _connected to check if it is already connected or not.
why is this prop protected? reason?

maybe a getter would be enough: get isConnected: () => this._connected

Hi, I would like to have this property too. Checking if the socket is connected or not is very useful.
By default a websocket expose those properties, why protect them ?

@haganbmj the issue is opened since 2017 and the feature wasn't planned for the V1 ?

Is this a thing yet? It's vital for my application.
