// 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) // --> "Thomas"

// 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()) // --> "Thomas"

// 3. Write a statement that calls Thomas's getName function,
// but returns "Amy".
console.log(thomas.getName() ? 'Amy' : 'Amy') // --> "Amy"

// 4. Remove the getName() method from all Person objects.
delete Person.prototype.getName
console.log(amy.getName()) // --> TypeError: Object [object Object] has no method 'getName'
