Reddit reviews Scala for the Impatient

1. Learning Scala is the easiest with Scala for the Impatient - most people I've introduced to Scala liked it.
   
2. To get deeper into Scala: Programming in Scala 3rd Edition - I've read the 1st version and it was a nice way to extends my knowledge.
   
3. Checkout the strategic scala style and the scalazzi safe scala subset to learn about the safe and effective usage of Scala.
   
4. Try IntelliJ Idea Community Edition with the "Scala" recommended plugin or try ensime with one of your favourite text editor.
   
5. Befriend SBT, the build tool - activator is a wrapper around SBT supporting play! framework and tutorial templates.
   
6. Try play! framework as a MVC framework - it's fast, easy and widely used amongst the Scala community.
   
7. Learn quill or slick to communicate with your database while exploiting Scala's functional/typesafe/macro capabilities.
   
8. Keep in touch with the community by r/scala, freenode/scala, gitter/scala and on other gitter rooms.
   
9. Embrace the functional concurrency - we've FP and we've referential transparency - therefore we can use Scala's non-blocking concurrency units easily - the Futures. There is also monix - a new tool for asynchronous programming, scala-async for the async/await model and Akka, an actor-based toolkit as the JVM's No1 distributed messaging API.
   
10. One of Scala's biggest selling point is Big Data and Statistics - apache spark is written in Scala and it's one of the fastest cluster computing tool around.
    
11. Scala is a multi-platform tool and it's present on the JVM and on js too by scala.js - you can write your scripts for browsers, use react/angular/etc. and run it on node.js. It's also coming to native by scala-native(LLVM-based).

I got a chuckle out of the Lol Monoid instance.

That, said, there's room for a "Haskell for the impatient"-style book.
