Get parent class name from child with ES6?

Question

I would like to get the parent class name (Parent), but I'm only able to retrieve the child class name with this code (Child)...

'use strict';  class Parent {  }  class Child extends Parent {  }  var instance = new Child(); console.log(instance.constructor.name);

Is it possible ?

Thanks !

ES6 classes inherit from each other. So when instance.constructor refers to the Child, then you can use Object.getPrototypeOf(instance.constructor) to get the Parent, and then access .name:

Object.getPrototypeOf(instance.constructor).name // == "Parent" 

Of course, full ES6 compliance and non-minified code are necessary for this to work. You should never rely on function names in code.
