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
• The Neophyte’s Guide to Scala http://danielwestheide.com/scala/neophytes.html
• Write Scala code for a few weeks/months.
• Do pair programming with experienced Scala devs.
• Install and configure scalafmt http://scalameta.org/scalafmt/
  • Just focus on the code, not the style.
• Go to gitter channels, people are really nice there.
  • https://gitter.im/scala/scala

Improving Scala/FP/Reactive Programming

• Akka
  • Akka in Action https://www.manning.com/books/akka-in-action
  • Effective Akka http://shop.oreilly.com/product/0636920028789.do
  • More: http://doc.akka.io/docs/akka/current/scala/additional/books.html
• Read about SBT (but not too much)
  • Keep your build.sbt simple, the less, the better.
• Install ammonite
• Stop using IntelliJ compiler, it’ll eventually lie to you. Always compile on SBT.
• Start reading the “red book” https://www.manning.com/books/functional-programming-in-scala
• Don’t throw Exceptions, use ADTs, Either
• Do Advanced Scala with Cats (underscore)
• Keep reading the “red book”
• Keep and eye on: Functional Programming in Scala for Mortals
  • https://leanpub.com/fp-scala-mortals
• Functional and Reactive Domain Modeling
  • https://www.manning.com/books/functional-and-reactive-domain-modeling
• Keep reading the “red book”
• Read more blogs, twitter about Scala.
  • From time to time, they will fight, just ignore them.
• read.andThen(practice).recoverWith(read)
• If you have plenty of time do the Coursera Courses (not sure if it’d worth it)

Read more about FP, Cats/Scalaz, Akka Streams, Monix, CQRS, and all the cool libs/patterns out there.
