In the middle of page 84, right after Listing 4.13, the arrow function in the listing is referred to and rewritten, this rewritten version of the arrow function has a space between the equal sign and greater than sign of the fat arrow("= >" instead of "=>") I don't know for sure that this would throw an error, but one es6 linter got confused when a space was in the middle of a fat arrow!

It's a layout error, and the whitespace should not be there.

It will be fixed in the next iteration.
