Well, your code loops through the string. On the second to last loop, it finds an "e", so result isn't null. It then loops again, finds no "e"s, and generates a "null", which gets written out to the browser.


Javascript isn't really my strong point, so there may be more elegant ways to do this, but this code would fix that issue, catching that final null:


<br />var patt1=new RegExp("e","g");<br /><br />do<br />{<br />    result=patt1.exec("The best things in life are frees");<br />    if (result != null) document.write(result);<br />}<br />while (result!=null)<br /><br />
