Array: built-in support for arraysECMAScript v1: Object → Array

Constructor

new Array( )

new Array(size)

new Array(element0, element1, ..., elementn)

Arguments

size: The desired number of elements in the array. The returned array has its length field set to size.
element0, ... elementn: An argument list of two or more arbitrary values. When the Array( ) constructor is invoked with these arguments, the newly created array is initialized with the specified argument values as its elements and its length field set to the number of arguments.

Returns

The newly created and initialized array. When Array( ) is invoked with no arguments, the returned array is empty and has a length field of 0. When invoked with a single numeric argument, the constructor returns an array with the specified number of undefined elements. When invoked with any other arguments, the constructor initializes the array with the values specified by the arguments. When the Array( ) constructor is called as a function, without the new operator, it behaves exactly as it does when called with the new operator.

Throws

RangeError: When a single integer size argument is passed to the Array( ) constructor, a RangeError exception is thrown if size is negative or is larger than 2³²−1.
