Adobe AIR & Flash programming language
Ranked in these QuestionsQuestion Ranking
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 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.
Pro Wide compatability
Runs on all major platforms as an AIR executable or mobile app, as well as in-browser as a FLASH file.
Teaches strong typed habits and follows many conventions of major programming languages.
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 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.
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.
