function Person(first, last, age, eye) {
    this.firstName = first;
    this.lastName = last;
    this.age = age;
    this.eyeColor = eye;

^ example of a good constructor

function Monster (name) {

^ start your attempt from that point.

Here's a few hints:

  • the instruction say to assign the property "Inside the constructor function"
  • the name of the property should be "name" (not "newMonster")
  • property names should be preceded by "this."
  • don't put quotes around the parameter name

Hi Bozin,

You want to use the .this syntax inside your constructor function.

You don't need to create a new instance of the constructor in the code challenge, all you do is set the properties of the constructor.


this.name = name
