What you need for this book 

You need to install Scala and Clojure. All the examples were tested with Scala version 2.11.7.  The Clojure examples were tested with Clojure version 1.6.0. You don’t need any IDE as most of the examples are small enough, so you can key them in the REPL (Read/Eval/Print Loop).

You also need a text editor. Use whichever you are comfortable with.
