Nice Content. Why this._subscriptions property is prefixed with underscore ? does it have any impact in javascript ?

It doesn't have impact. Just a naming convention to denote that the field should be considered internal property. Private fields are yet not widely supported in classes across browsers.

I'm not sure whether this code works with multiple subscriptions on the same instance with the same function name??

Can you share a code example where it is failing?
