Haxe

Haxe is an open source high-level multi-platform programming language and compiler that can produce applications and source code for many different platforms from a single code-base.

Haxe includes a set of common functionality that is supported across all platforms, such as numeric data types, text, arrays, binary and some common file formats. Haxe also includes platform-specific API for Adobe Flash, C++, PHP and other languages.

Code written in the Haxe language can be source-to-source compiled into ActionScript 3 code, JavaScript programs, Java, C#, C++ standalone applications, Python, PHP, Apache CGI, and Node.js server-side applications.

Haxe is also a full-featured ActionScript 3-compatible Adobe Flash compiler, that can compile a SWF file directly from Haxe code. Haxe can also compile to Neko applications, built by the same developer.

Major users of Haxe include TiVo, Prezi, Nickelodeon, Disney, Mattel, Hasbro, Coca Cola, Toyota and BBC.OpenFL and Flambe are popular Haxe frameworks that enable the creation of multi-platform content from a single codebase. With HTML5 dominating over Adobe Flash in recent years, Haxe, Unity and other cross-platform tools are increasingly necessary to target modern platforms while providing backward compatibility with Adobe Flash Player.
