I was reading through the early parts of the book on my Kindle. I noticed a couple things in the .mobi version on Kindle (2nd gen).
The line: console.log
impatient ? useBackticks() : learnCoffeeScript()
does not wrap. On the next to smallest font size in portrait mode, some of that line is never shown.
The other text in the same box is smaller than the rest and makes it a little more challenging to read.
That said, it is a good start. I’ll continue to read and learn.
