Getting started with Scala

At the time of writing, Scala Version 2.12.8 (https://www.scala-lang.org/) is the most recent version of the language. We have the option of running Scala code online using our browser or installing and running it on our machine. Running it online is good for getting started with Scala as a first step; however, you will need to install it on your computer to learn the language's in-depth features and make use of it for data analysis.
