Just by looking at the ToC I’ve a hard time understanding the intended audiences of this book. Since CoffeeScript is such a minimal language on top of JS, I have a feeling that the online documentation (http://jashkenas.github.com/coffee-script/) pretty much covered everything you need to know if you are already familiar with JS. Can someone enlighten me on who would (or why would I) find this book useful? :)
Additionally, the features documented at CoffeeScript.org are explained in greater detail, along with their rationales. Rather than just “This code does that,” it’s more “This code does that this way, and here’s why, and here’s a common mistake to watch out for.”
this!) and getting into the JS mentality. I was worried about purchasing the book without having extensive JS experience and figured I might have to brush up using other sources but I’m finding it just about right for my level.
