Confusion by naming conventions owner(owner)= owner...

I always get confused by these naming conventions;

set owner(owner) { this._owner = owner; }

So the setter method is called "owner" and the parameter is called "owner" and then the property is also called "_owner"

How do I distinguish later what I'm referring to?

Wouldn't it be more understandable to write something like:

set ownetSet(ownerPar) { this.ownerProp = ownerPar; }

Am I missing something important?

Your alternative would also work just fine. But remember that the scope of the parameter is limited to function, so you won't need to (or be able to) access it directly later. That's why it's being copied into the private field.

And the private field can be identified by the underscore in front of the name, which is a naming convention that implies a private field.
