I'm sure someone's already done this, but since I've got a TiVo and can do it too, here's the list of corrections that display in the Simpson's episode "Homer Badman" during the "Rock Bottom" corrections bit.

I couldn't remember how to clone arrays in JavaScript, so I did a quick search for the answer.

I found some, uh, not-so-great answers, mainly involving writing custom copy functions that iterated over every item in the array to copy it.

Turns out there already exists a method in JavaScript 1.2+ (in other words, in all major browsers) to clone arrays. It's called, helpfully enough, slice(begin[,end]).

So I've got the following code:

var e = document.createElement("div");
e.appendChild(document.createTextNode("Some text"));

This generates a warning and one error, which are underlined above with a yellow and red line, respectively.
