How to get derived class name from base class?

Question

Is is possible to get derived class name from base constructor?

class Entity {
    constructor() {
         // how to log here a class?
         console.log('a')
    }
}
class a extends Entity {}
new a()

You can output the name of a function in JavaScript/TypeScript using Function.name , see this answer :

 class Entity { constructor() { console.log(this.constructor.name) } } class A extends Entity {} const a = new A(); console.log(a.constructor.name);
