What first attracted me to this book is its coverage of several languages that I know little or nothing about. For reasons mostly due to chance, I’ve been exposed to only a handful of well-known programming languages during my professional career. Recently, I’ve been quite intrigued by Erlang’s concurrency model and robustness even though there is no place for it in my day-day tasks. Having the opportunity to read about Erlang being evaluated against other languages was just what I wanted. So, I took the red pill and found out just how deep the rabbit hole goes.
