Name

Array

Constructor

new Array( )             // empty
new Array(n)            // n undefined elements
new Array(e0, e1,...)   // specified elements

Literal Syntax

In JavaScript 1.2, JScript 3.0, and ECMA v3, you can create and initialize an array by placing a comma-separated list of expressions within square brackets. The values of these expressions become the elements of the array. For example:

var a = [1, true, 'abc'];
var b = [a[0], a[0]*2, f(x)];

Properties

length

A read/write integer specifying the number of elements in the array, or, when the array does not have contiguous elements, a number one larger than the index of the last element in the array. Changing the value of this property truncates or extends the array.
