When comparing Scala vs Actionscript, the Slant community recommends Scala for most people. In the question“What is the best programming language to learn first?” Scala is ranked 27th while Actionscript is ranked 77th. The most important reason people chose Scala is:
The immutable values make it perfect for working with concurrency

Pros
Pro Immutable values
The immutable values make it perfect for working with concurrency
Pro Multiparadigm
Scala supports both Functional and Object Oriented styles of programming. Beginners can learn both paradigms without having to learn a new language, and experts can switch between the two according to what best suits their needs at the time.
Pro Type inference
Scala offers type inference, which, while giving the same safety as Java's type system, allows programmers to focus on the code itself, rather than on updating type annotations.
Pro Compiles to JVM bytecode
Aside from Java itself, Scala is by far the most popular of the many JVM languages. If you're developing for Android, or a similar JVM-only platform, or otherwise need out-of-the-box cross-platform compatibility, but the performance of a compiled language, Scala is the way to go.
Pro Very good online courses
On coursera you can find great introduction to Scala by Martin Odersky.
Pro Type inference leads to a simpler syntax
Pro Expressive functional programming abstraction for reusable and safe code
Pro Great for light games
Easy 2D and rich 3D capabilities means ActionScript is a great game prototyping or production tool. Relatively easy to get images on a stage and easy to share with it's wide platform support.
Pro Wide compatability
Runs on all major platforms as an AIR executable or mobile app, as well as in-browser as a FLASH file.
Pro Object-oriented
Teaches strong typed habits and follows many conventions of major programming languages.
Pro Large community
Online games and a colorful history means there are a lot of existing scripts and examples on the internet for available integration as well as tutorials.
Cons
Con Can be intimidating for beginners
Scala is an industrial language. It brings functional programming to the JVM, but not with a "start small and grow the language" perspective, but rather a very powerful language for professional programmers.
Con Way too complex for beginners
Even for seasoned programmers it's a difficult language.
Con Static type system inherits cruft from Java
The type system is too complicated yet still less powerful than Haskell's.
Con No future
The last stable release is : 3.0 / June 27, 2006. Adobe confirmed there will be no 4.0, ever. This train has stopped long time ago.
Con Not very widely used
Past its hay-day, ActionScript is reserved for more niche products. This in turn means that choosing ActionScript as a career path is often ill-advised. Exceptions include ScaleForm for UI/UX in games (including AAA games) and light apps and games.
Con Waning support
Un-usable in-browser on most mobile devices, ActionScript is used mainly for niche AIR programs, graphical mobile and in-browser apps and games, and in UI/UX using Scaleform.
