| Question ID 14852 | You are creating a class named Consultant that must inherit from the Employee class. The
Consultant class must modify the inherited PayEmployee method. The Employee class is

function Employee() {}
Employee.prototype.PayEmployee = function ( ){
alert('Hi there!');
Future instances of Consultant must be created with the overridden method.

| Option A | Consultant.PayEmployee = function () { alert('Pay Consulant'); }
|
| Option B | Consultant.prototype.PayEmployee = function () { alert('Pay Consultant'); }
|
| Option C | function Consultant () { Employee.call(this); } Consultant.prototype = new Employee(); Consultant.prototype.constructor = Consultant;
|
| Option D | function Consultant() { Employee.call(this); } Consultant.prototype.constructor = Consultant.create;
|
| Correct Answer | B,C |
Explanation Explanation: * Object.prototype.constructor Returns a reference to the Object function that created the instance's prototype. Note that the value of this property is a reference to the function itself, not a string containing the function's name. The value is only read-only for primitive values such as 1, true and "test". * The constructor property is created together with the function as a single property of func.prototype.
