Sure! I have the table of contents for "Scala for the Impatient" open in front of me:
- S4tI goes into a lot more detail into language features: custom extractors, abstract overrides, annotations, higher kinded types, custom operators. Hands-on Scala skips all of that. Most developers do not need to know this stuff to get stuff done professionally.
- Hands-on Scala spends its pages working on fun use cases instead! As far as I can tell, S4tI doesn't cover use cases at all. Sure it's great you know about structural/compound/existential types, but it's setting up webserver, mangling a database, or scraping someone's website that gets you paid a salary.
- S4tI is a bit out of date (at least the preview copy I have) and covers things like Delimited Continuations, XML processing, and the scala-parser-combinators and scala-actors libraries which you shouldn't really be using any more
- S4tI doesn't really use third party libraries AFAIK; that means things like working with files uses the `java.io` or `scala.io` APIs, which are strictly worse than the modern alternatives. In fact, it is only due to the modern collection of libraries such as Requests-Scala, OS-Lib, Cask, Quill, etc. that allows Hands-on Scala to cover as much ground as it does in a tiny amount of code. Hands-on Scala leverages this ability to the fullest!
