Dynamic HTML: The Definitive Reference

Name

new — NN 2 IE J1 ECMA 1

Synopsis

The new operator. This operator creates instances of the following static objects:

• Array

• Boolean

• Date

• Function

• Number

• Object

• RegExp

• String

An expression with this operator evaluates to an instance of the object. Syntax rules allow naming the static object, the static object with empty parentheses, and the static object with parameters in parentheses:

var myArray = new Array
var myArray = new Array()
var myArray = new Array("Larry", "Moe", "Curly")

Only the last two examples are guaranteed to work in all scriptable browser versions. With the exception of the Date object, if you omit assigning parameters during the object creation, the newly minted instance has only the properties that are assigned to the prototype of the static object.

Example

var now = new Date()
