“It’s been a lot of fun, and surprisingly little work to get a language that covers 95% of what JavaScript can do.”
— Jeremy Ashkenas, created CoffeeScript after reading the book.
“I love this book! It helped me create my own Awesome-to-PHP compiler. It’s not a full featured compiler yet but I had a lot of fun coding it and I learned a LOT.”
— Julien Desrosiers, created Phlower after reading the book.
“I never had a chance to study language internals at university, and while very interested, I found their inner workings intimidating. With this course I’ve found a simple but engaging introduction to the world of lexers, parsers, interpreters and compilers, and suddenly a whole new world in programming has opened up. Highly recommended.”
— David Bolton
