Exercise 8 for JavaScript Masters class

08_inheritance.js

// 1. Write a class to support the following code:

var Person = function(name) {
    this.name = name;
}

var thomas = new Person('Thomas');
var amy = new Person('Amy');

console.log(thomas.name); 
console.log(amy.name); 

// 2. Add a getName() method to all Person objects, that outputs
// the persons name.

Person.prototype.getName = function() {
   return this.name;
}

console.log(thomas.getName()); 
console.log(amy.getName());

// 3. Write a statement that calls Thomas's getName function,
// but returns "Amy". (Don't change or redefine the getName 
// function in any way.)

console.log(function() {thomas.getName(); return "Amy"; }()) ;

// 4. Remove the getName() method from all Person objects.

delete Person.prototype.getName;

console.log(thomas.getName());
