This an example of how to implement a "Hello World" Haxe, with source code and support files: build.hxml, compile.txt, Haxe.hx, Haxe.js (generated file, from Haxe.hx), HelloWorld.html, javascript.js

Related to Haxe programming language: Some time ago, I have posted comments about "Haxe in Haxe" at github / HaxeFoundation. The concept in that post is similar to a bootstrap compiler, but it is not the same.
