Array Object
You can use the Array object to create arrays in script. An array is an indexed data structure for storing information of related type in script.

Constructor

[new] Array() Creates and returns a new Array object of length 0.
[new] Array(size) Creates and returns a new Array object of length size.
[new] Array(element0, element1,,elementn) Creates and returns an Array object of length n. The elements of the array are specified by the supplied arguments element0, element1,...,elementn. String arguments must be quoted.

Instance Properties

length The number of elements in the array.

Instance Methods

concat Forms a new array by adding elements to the calling array.
join Concatenates the elements of an array to form a single string.
pop Removes and returns the last element in the calling array.
push Adds elements to the end of the calling array.
reverse Reverses the order of elements in the calling array.
shift Removes and returns the first element of the calling array.
slice Returns a portion of the calling array.
splice Removes and/or replaces elements in the calling array.
sort Sorts the elements of the calling array.
toString Converts the elements of an array to a single string.
unshift Inserts elements to the beginning of the calling array

Example

The following examples demonstrate three uses of the Array object constructor.
    //Creates a new array, Arr1.
    //Arr1 is an empty array.
    var Arr1 = new Array();

    //Creates a new array, Arr2.
    //Arr2 is an empty array,
    //but it has memory to hold five elements.
    var Arr2 = new Array(5);

    //Creates a new array, Arr3.
    //Arr3 contains three string elements.
    var arr3 = new Array("Mercury", "Venus", "Earth");
