Great content but far too many typos
I bought the physical copy of this book and have been very pleased so far with the content, being at chapter 4. Guillermo does a great job explaining the concepts of Node, like the event loop, etc, and he explores useful concepts that I've seen other books leave out. His examples are helpful when they work. That's the only problem I have with this book; it has far too many typos (again, I'm only on chapter 4). Some are small, like spelling "buffer" with 3 f's or spelling "announce" with an e and 1 n, but others are large and confusing. For example, Guillermo shows an example of how to use the Buffer class to load an image and write it to the file system. The example code writes a PNG file but the text he writes corresponding to the example, and the screenshot he shows, both reference the file as a GIF. I tried several things to get this example to work, but the file always came out corrupted. I'll probably still go back and read this book because it has been very helpful, like I said above, in exploring different concepts and explaining what is possible. But I'm going to read the Node Beginner Book first so that I get a good ground work. Being that the amount of typos were so frustrating that I had to stop reading the book, I can only give 3 stars.
