Array extensions are part of the Microsoft AJAX Library. They add static methods to the JavaScript Array object for additional functionality.

For more information about the JavaScript object that these static methods extend and about its constructor, see Array Object in the Language Reference.


The following example shows how to create a new Array object and invoke the Microsoft AJAX Library add function to add arrays as an element to a single array. The multidimensional array is then passed to a function that displays the array as a table in the document.
