Get child class name

Question

Is there a way to get class name that extends the class?

class Foo {
  constructor(){
    console.log(extendedBy.name);//extendedBy.name to be replaced with "Bar"
  }
}

class Bar extends Foo {
  constructor(){
    super();
  }
}

I tried using Google and Stack but only found how to get the parent (I.E. Foo) name.

Thanks in advance.

Check the this.constructor.name :

class Foo {
  constructor(){
    console.log('Foo extendedBy : ', this.constructor.name);
  }
}

class Bar extends Foo {
  constructor(){
    super();
  }
}

class OtherBar extends Foo {
  constructor(){
    super();
  }
}

class ByBar extends Bar {
  constructor(){
    super();
  }
}

const MyBar = new Bar();
const MyOtherBar = new OtherBar();
const FromBar = new ByBar();

Thanks! Didn't found this before – Dan B. Oct 02 '19 at 16:07
Better yet, use `new.target.name` – Bergi Oct 02 '19 at 18:38
