Is there a concrete example of the Python-like code vs the more complex ones? I appreciate the help.
I'm thinking what language next should I pick up. It is either OCaml or Scala.
Haha this book is going to be 400 pages of concrete examples. It's not out yet, so you'll have to take my word for it for the next few weeks while the last round of reviews and editing are incorporated into the manuscript. If you're interested, put your email down and I'll let you know when it's ready!
Scala is a pretty great investment for services, big data, etc. It has a robust ecosystem.
However, the compiler is slow, and startup time can be slow (and Graal and Scala Native just aren't options yet), and if I want to make some tool that gets called fast in a loop or deploys as a "small", native binary, OCaml is nice alternative which I prefer to the only other compelling entry in this area, Go.
