Use constructors to create objects
A constructor is a function that calls it to demonstrate and initialize special types of objects. You can use the new keyword to call a constructor. The following is a new example of using constructors.
Var myObject = new Object (); // create a common Object without attributes.
Var myBirthday = new Date (1961, 5, 10); // create a Date object.
Var myCar = new Car (); // create a user-defined object and initialize its attributes.
The constructor transmits a parameter as the value of the specific this keyword to the newly created null object. Then, the constructor is responsible for initializing the new object (creating attributes and providing their initial values ). After completion, the constructor returns a parameter of the object it constructs.
Compile Constructor
You can use the new operator to create and initialize an Object with predefined constructors such as Object (), Date (), and Function. Object-Oriented Programming its powerful feature is the ability to define custom constructor to create custom objects used in scripts. A user-defined constructor is created to create objects with defined attributes. The following is an example of a user-defined function (note the use of this keyword ).
Function Circle (xPoint, yPoint, radius ){
This. x = xPoint; // The x coordinate of the center.
This. y = yPoint; // y coordinate of the center
