I'm not sure I understood you correctly, you mean using this I can create another class that will extend the SingletonClass? Then SingletonClass isn't a singleton, because, by definition, it cannot be extended.
Plus, I have tried something like this and failed, can you provide the code?
Regardless singleton is right or not, there is a way to create a class, that can be extended and be a singleton for own type only.
Instead of using hard reference class constructor you should use constructor property of the instance.
this.constructor
is a reference to the direct constructor function.I'm not sure I understood you correctly, you mean using this I can create another class that will extend the
SingletonClass

I forgot about constructors prototype chain :P
Here you have working example:
This is not a singleton class now :) But nevertheless, excellent example.
