RegExp $+ (6)

The RegExp.$+ property represents the last parenthesized substring pattern match. This is the same as using the lastParen property. <html>     <body>     <script language="JavaScript">     <!--     exp = new RegExp("(is)", "g");     str = "This is a test (is)!";     myArray = exp.exec(str);     document.write("The RegExp.lastParen is: " + "<b>"+ RegExp.lastParen + "</b>");     -->     </script>     </body>     </html>
