javascript Array toLocaleString( )

Returns a comma-delimited string of values, theoretically in a format tailored to the language and customs of the browser's default language. Implementation details vary with browser and data type. IE 5.5 and later converts numbers of all kinds to strings with two digits to the right of the decimal, but triggers an error for object references. Netscape 6 leaves integers in their original format and displays object references as [object objectType]. The ECMA standard leaves such interpretations up to the browser maker.
