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

[@DevtoolsTech]

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.

good content

[@sarang1040]

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

[@DevtoolsTech]

Can you share a code example where it is failing?
