Appeared exactly when I needed it. I'm currently exploring the JS web app world, and I am in need of some guidance. Sometimes I struggle because my flow currently consists of taking apart other JS apps, instead of having a solid foundation and implementing my own solutions.
There are some things that just aren't intuitive, when you're reading other people's code. I hope this book either enables me to write code from scratch or significantly speeds up my "decompiling" of other people's code.
Congrats on the launch! Must've been quite a ride, since from what I read, you're traveling the world and surfing. Nicely done.
