Object-Oriented JavaScript Challenge 1 of 2

Man I've been entering the code into the person.js. Just read TEACHER TAB in the comment above a noticed me fault.

Thanks Daryl

I know this may seem odd but to pass the first step of the challenge you have to remove the stuff already in the Teacher object. Then you use the Person.call. Put this code in your teacher.js and nothing else:

function Teacher(firstName, lastName, roomNumber) {
  Person.call(this, firstName, lastName);
  this.room = roomNumber;
}

Hey its telling you to call the Person constructor in the Teacher constructor. The call method lets you apply a function changing the this. So here the this is the teacher and allows you to set the given arguments using the methods in the Person constructor. Below is the code you need;

function Teacher(firstName, lastName, roomNumber) {
  Person.call(this, firstName, lastName)
  this.room = roomNumber;
}

I've tried all possible options, with and w/o the roomNumber option and nothing passes. The roomNumber argument isn't even mentioned in part 1 of the challenge so if it is the key Treehouse should fix it but the people at Treehouse say the code works on their end so....I'm stuck here with every section of the Developer Track complete but this one question.

function Person(firstName, lastName) { this.firstName = firstName; this.lastName = lastName; }

Person.prototype.fullName = function() { return this.firstName + " " + this.lastName; };

function Teacher(firstName, lastName, roomNumber) { Person.call(this, firstName, lastName) this.room = roomNumber; }

i think the reason the answer isn't passing because it's looking for the this.room = roomNumber line as well. Looks like your answer had only the Person.call line.
