Pragmatic Scala: Create Expressive, Concise, and Scalable Applications. 1st. Edition.

My highlights and comments

"Using the REPL

Quite a few languages provide a REPL—read-eval-print loop—a tool that’s a convenient way to key in snippets of code and interactively see the code come to life immediately. In addition to executing code snippets, REPLs often provide details that are not easily accessible at runtime. That makes REPL a special tool for experimentation and also to learn how the language infers types for variables and functions." (Chapter 2)

I have used the REPL for learning Scala while taking this course: Lightbend Scala Language - Professional, by Lightbend, Course Staff Petro Verkhogliad.
