Synopsis

array.toString( )

Returns

A string representation of array.

Throws

TypeError

If this method is invoked on an object that is not an Array.

Description

The toString( ) method of an array converts an
array to a string and returns the string. When an array is used in a
string context, JavaScript automatically converts it to a string by
calling this method. On some occasions, however, you may want to call
toString( ) explicitly.

toString( ) converts an array to a string by first
converting each of the array elements to strings (by calling their
toString( ) methods). Once each element is
converted to a string, it outputs them in a comma-separated list.
This return value is the same string that would be returned by the
join( ) method with no arguments.

Bugs

In Netscape implementations, when Version 1.2 of the language is
explicitly specified, toString( ) returns its list
of comma-and-space-separated array elements within square brackets
using array literal notation. This occurs, for example, when the
language attribute of a
<script> tag is explicitly specified as
"JavaScript1.2".
