Actionscript has basically no error checking. It'll check for syntax errors and that about it - every other error manifests as a strange bug or "why the F* is nothing happening!?!" Then you spend an hour tracking it down and discover the cause was some trivial thing that any normal language would have simply raised a compiler error for in the first place.
And on top of that, its libs are very callback-heavy even in places where a synchronous option should have been available, so even very basic sequential code sometimes gets turned into a messy chain of callbacks.
That's why I made a beeline for the "ActionScript - Dislike" button.
Are you serious? When's the last time you used ActionScript, 2004? Modern AS3 compiled using the FlexSDK is a proper development environment with compile-time errors for types and all. Combined with a debug player, you get both compile-time and runtime errors.
It certainly has a hell of a lot more error checking going on than something like JavaScript by the virtue of being a statically typed language first with dynamic stuff second.
That's not to say that obscure bugs don't exist in the runtime as with every other runtime ever, but don't misrepresent something you don't seem to be well versed in.
