There should be an 'Answers on page 63.' notice somewhere on that page.

Just Do It Solutions

This is referring to text-utils.js

I am not an expert on Javascript but to the best of my knowledge childNode.normalize
does not exist. I cannot find any reference to it on Google.
Also childNode.nodeType returns an integer, not a text value.

So by commenting out childNode.normalize() and changing childNode.nodeType == 3 I was
able to get the code running.
