Wrong URI for the browser-based CoffeeScript compiler

[fvictorio]

In chapter 1, it says:

In fact, you can use the browser-based CoffeeScript compiler yourself, by including this script in a
page, marking up any CoffeeScript script tags with the correct type.

But both the link in that paragraph (http://jashkenas.github.io/coffee-script/extras/coffee-script.js) and the one used in the script below don't exist. I used https://raw.githubusercontent.com/jashkenas/coffeescript/master/extras/coffee-script.js and that worked, but probably there is a better option.

Thanks for the book.
