I am still reading it at the moment, but have come across a mistake on page 50 on the third paragraph under the Strings section. In parenthesis on the last sentence of the paragraph, it says "(for example "this is not right" isn't a valid string because it begins with a double-quote mark and ends with a single quote)." However, it actually begins and ends with a double quote which would make it valid.
Thanks for bringing that to our attention. It looks like this errata was also posted earlier this year but has yet to be addressed and updated:
