The Haxe Foundation recently released Haxe 4.0 and I decided to check it out. Here’s what’s new in version 4. Haxe runs on Windows, Mac, and Linux. You can download it here. What is Haxe? According to the website: Haxe is an open-source high-level strictly-typed programming language with a fast optimizing cross-compiler. So the high level strictly typed programming language makes sense, but a fast optimizing cross compiler? What’s that about?
