The Whack engine will be an alternative to the React framework and will target HTML5 and Node.js®, compiling ActionScript 3, MXML and CSS (1-1 mapping to AS3) without any bond with Adobe Flash, bundling a framework that accelerates UI creation and more.
Visual Studio Code
Thanks to the help I got in the URLO forum and other places, the Whack language server and package manager has made progress. Status bar and diagnostics are basically in-place.
Hover isn't complex to implement, but I'm relaxing a bit for now.
Serializable + clone
You'll be able to naturally clone class objects and (de)serialize from/into class objects:
// object:*
object.clone()
// or
Object.clone(object)
// deserialization
JSON.parse(str, T)
// serialization
JSON.stringify(object)
