Usage

new constructor()

Parameters

constructor A function followed by any optional parameters in parentheses. The function is usually the name of the object type (for example, Array, Number, or Object) to be constructed.

Returns

Nothing.

Description

Operator; creates a new, initially anonymous, object and calls the function identified by the constructor parameter. The new operator passes to the function any optional parameters in parentheses, as well as the newly created object, which is referenced using the keyword this. The constructor function can then use this to set the variables of the object.

Example

The following example creates the Book() function and then uses the new operator to create the objects book1 and book2.

function Book(name, price){
  this.name = name;
  this.price = price;
}

book1 = new Book("Confederacy of Dunces", 19.95);
book2 = new Book("The Floating Opera", 10.95);

Example

The following example uses the new operator to create an Array object with 18 elements:

golfCourse_array = new Array(18);
