So I really have no idea what to do here. Can anyone show me what the challenge wants me to do?
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;
}

Teacher.prototype = Object.create(Person.prototype);

16,594 PointsI'm starting to think Andrew got the hardest courses to teach. Apparently there's no simple way to learn this stuff.
It's a lot to keep track of. Referring back and forth to different codes and objects, learning DRY...I keep looking at all the different comments, I guess the idea is just keep at it till it starts to make sense. I know some people just get it, I'm happy for them. The rest of us just need to persevere.
