Any constructor exposes a property name, which is the function name. You access the constructor via an instance (using new) or a prototype:

function Person() {
  console.log(this.constructor.name); //Person
}

var p = new Person();
console.log(p.constructor.name); //Person

console.log(Person.prototype.constructor.name);  //Person
