Is anything wrong of my code? Teacher.prototype = Object.create(Person, prototype);

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

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

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

  this.room = roomNumber;
}

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

This might just be a typo .. did you mean to pass Person.prototype to the Object.create method (instead of Person, prototype)?
