Nice. I personally like explicit types because it’s more human readable.
How feasable would it be to automatically add types to the code based on type inference. So var s = “hello” could be transformed to var s:String = “hello”. Do you need to assign the variable when it’s declared for this to work? > On Jun 21, 2023, at 12:07 AM, Josh Tynjala <joshtynj...@bowlerhat.dev> wrote: > > Hi all, > > One cool feature in other languages similar to AS3, such as TypeScript or > Haxe, is type inference.
