Please give me a explain and a real exact answer to this challenge cause it's very annoying, (stuck for days.)

function Teacher(firstName, lastName, roomNumber) { person.call(this, firstName, lastName ); this.room = roomNumber; } Person.prototype.fullName = function() { return this.firstName + " " + this.lastName; };

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

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

You need to change to the teacher.js file (it looks like you are editing the person.js file).

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

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

Also, JavaScript is case-sensitive so person is not the same as Person.
