remains is not defined

[sterlinglemon]

There is a Reference not defined exception at: alpaca-trade-api-js/lib/resources/websockets.js Line 172.

Change
remains = Object.keys(this.subscriptionState)
To
let remains = Object.keys(this.subscriptionState)

This fixes the exception, however the client still is subscribed to the given keys after calling the unsubscribe method. All this method seems to do is alter the subscription list but it fails to fully unsubscribe from the given keys.

Thanks for pointing this out. Unsubscription is currently not actually supported by the Alpaca API, only by Polygon. I'll be removing this misleading method in our next release.
