If you want to learn Scala, I’d suggest:

• Install IntelliJ + Scala Plugin
• Don’t do the Coursera courses yet.
• Don’t do the “red book” Functional Programming in Scala yet.
• Do: http://underscore.io/books/
  • Essential Scala
  • Essential Play
  • Essential Slick
• Do Scala for the Impatient: https://www.amazon.com/Scala-Impatient-Cay-S-Horstmann/dp/0321774094

  // Various necessary imports. Notes:
  //
  // 1. fs2 is necessary. See https://github.com/functional-streams-for-scala/fs2
  // 2. streamz is necessary. See https://github.com/krasserm/streamz
  // 3. Apache Tika is used to infer MIME types from file names, because it's more reliable and
  //    fully-featured than using java.nio.file.Files.probeContentType().
  //
  // If using SBT, you'll want these library dependencies and resolvers:
