24.18.2. 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 array element to strings (by calling its toString( ) method). Once each element is converted to a string, toString( ) 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.
