When I was browsing a Web template site, I found a funny bug: The buttons are all undefined.
undefined is a data type in ECMAScript where the variable is not defined or does not exist, the following code makes variable x undefined:

var a = new Object(); //variable a is now an object
a.b = 12; //a has b now, it's 12
var x = a.d; //a doesn't have property d, so it's undefined.

javascript:alert(0 / 0)

Undefined, not-a-number, name output, and general errors are some of my favorite types, especially when it's on a professional program in beta stage--or even better, the finished product!

And

javascript:alert(1 / 0)

That is the punishment for making a Web template that is very inaccessible.

javascript: alert(0 / 0)

Heh, I've seen that "undefined" on YouTube when uploading videos before. And the new code does produce "NaN".

The Buizel.Net Jukebox has NaN. Refresh any page while the Jukebox is open.
