How to create Objects using JavaScript Object Constructor - JavaScript Tutorial 78

Notes for You:: How to Create Objects using JavaScript Object Constructor - Tutorial 78
- If we want to create multiple objects of same type, then we take help of constructor function
- Constructor function helps us to define a constructor for any object type.

Object type [class]
- is a combination of its constructor and its prototype.

Constructor:
- is a special function responsible for constructing new object and called as soon as a new object is created.

Prototype:
- is a special object contains shared properties and behaviors of instances.

Example:
- Rectangle : object type
- rect1,rect2 … : objects or instances of Rectangle object type
- function Rectangle(width,height){ }: constructor function for Rectangle object type

Syntax:
// Defining a constructor function
function ObjectTypeName( [value1, value2, …. ]) {
…
}

// Creating new objects
var objectName = new ObjectTypeName ([param_list]);

Example Code:
// Definition of constructor function for Rectangle type
function Rectangle(width,height) {
{
};
}
// Creating new rect1 object using Rectangle type
var rect1 = new Rectangle(5,5);
