The RegExp.$' property represents the substring following the most pattern match.
This is the same as using the rightContext property.
<html> <body> <script language="JavaScript"> <!-- pat = /is*/gi;
var str = "This is a test."; myArray = pat.exec(str); document.write("The RegExp.rightContext is: " + RegExp.rightContext); --> </script> </body> </html>
