What does those numbers mean? Is it hidding something?

[AFN]

Have a question, how come when I view this file “http://www.dynamicdrive.com/emailriddler/encryption.js”
it is like this “var erarray= new Array(118,97,114,32,100,111,109… …50,48,48,41,10,125)
var ersource=''
for (i=0;i<erarray.length;i++)
ersource+=String.fromCharCode(erarray[i])

document.write('<script type="text/javascript">'+ersource+'<\/script>')
<script type="text/javascript">'+ersource+'<\/script>

What does those numbers mean?

They're the hexadecimal ASCII values of characters. And yes, it's hiding the actual code which is created by translating those values back into the characters they represent.
