Haxe

Haxe is a <a href="/facts/High-level_programming_language/smjECUhx">high-level</a> <a href="/facts/Cross-platform/16zqdvNR">cross-platform</a> <a href="/facts/Programming_language/cWTYbgWa">programming language</a> and <a href="/facts/Compiler/WNfCDFJe">compiler</a> that can produce applications and <a href="/facts/Source_code/o9J6Jv23">source code</a> for many different <a href="/facts/Computing_platform/DmKwp5Bk">computing platforms</a> from one code-base. It is <a href="/facts/Free_and_open-source_software/1cHtjLCB">free and open-source software</a>, released under an <a href="/facts/MIT_License/8llAQtlk">MIT License</a>. The compiler is written in <a href="/facts/OCaml/ThBGLND8">OCaml</a>. It can be run in server-mode to provide code completion for <a href="/facts/Integrated_development_environment/jbEINSQf">integrated development environments</a> (IDEs).
Haxe includes a set of features and a <a href="/facts/Standard_library/g9QS3vy0">standard library</a> supported <a href="/facts/Cross-platform_software/16zqdvNR">across all platforms</a>, including <a href="/facts/Integer_(computer_science)/zWabo5M9">numeric data types</a>, <a href="/facts/String_(computer_science)/4ChJu5WS">strings</a>, <a href="/facts/Array_data_type/gHJJ3XPw">arrays</a>, <a href="/facts/Associative_array/IFGd2xcP">maps</a>, <a href="/facts/Binary_file/ysttM8hh">binary</a>, <a href="/facts/Reflective_programming/Nj8stFfp">reflective programming</a>, maths, Hypertext Transfer Protocol (<a href="/facts/HTTP/TWtvf7JD">HTTP</a>), file system and common <a href="/facts/File_format/qrXbwJaH">file formats</a>. Haxe also includes platform-specific application programming interfaces (<a href="/facts/API/GMlN4vUr">APIs</a>) for each compiler target. Kha, <a href="/facts/OpenFL/2xv9HJoG">OpenFL</a>, and Heaps.io are popular Haxe frameworks that enable creating multi-platform content from one codebase.
Haxe originated with the idea of supporting <a href="/facts/Client-side/v7DVfjsH">client-side</a> and <a href="/facts/Server-side/JqukWyaA">server-side</a> programming in one language, and simplifying the communication logic between them. Code written in Haxe can be <a href="/facts/Source-to-source_compiler/MnSVwoe9">compiled</a> into <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a>, <a href="/facts/C%252B%252B/Et0F2qn9">C++</a>, <a href="/facts/Java_(programming_language)/9ScgFyAL">Java</a>, <a href="/facts/Java_virtual_machine/l9Nzrsun">Java virtual machine</a> (JVM), <a href="/facts/PHP/vU6YRJX0">PHP</a>, <a href="/facts/C_Sharp_(programming_language)/UC2gxeyb">C#</a>, <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a>, <a href="/facts/Lua_(programming_language)/xkBCgta0">Lua</a> and <a href="/facts/Node.js/FKzhV4Qa">Node.js</a>. Haxe can also directly compile <a href="/facts/SWF/5qwLlUC5">SWF</a>, HashLink, and <a href="/facts/NekoVM/8mssM1hE">NekoVM</a> <a href="/facts/Bytecode/EPkMFR7M">bytecode</a> and also runs in interpreted mode.
Haxe supports externs (definition files) that can contain <a href="/facts/Data_type/fcx5hgVL">data type</a> information of extant <a href="/facts/Library_(computing)/xRzL3P7q">libraries</a> to describe target-specific interaction in a type-safe manner, like <a href="/facts/C%252B%252B/Et0F2qn9">C++</a> <a href="/facts/Header_files/fg3KEG4V">header files</a> can describe the structure of existing <a href="/facts/Object_file/sFBvosE4">object files</a>. This enables to use the values defined in the files as if they were statically typed Haxe entities. Beside externs, other solutions exist to access each platform's native abilities.
Many popular <a href="/facts/Integrated_development_environment/jbEINSQf">IDEs</a> and <a href="/facts/Source_code_editor/D0hecHMt">source code editors</a> have support available for Haxe development. No particular development environment or tool set is officially recommended by the Haxe Foundation, although <a href="/facts/VS_Code/YsBDgKlK">VS Code</a>, <a href="/facts/IntelliJ_IDEA/h689XrQz">IntelliJ IDEA</a> and HaxeDevelop have the most support for Haxe development. The core functionalities of <a href="/facts/Syntax_highlighting/cLCr5a6w">syntax highlighting</a>, <a href="/facts/Code_completion/eLNAGYlS">code completion</a>, <a href="/facts/Refactoring/gkw9oVTE">refactoring</a>, <a href="/facts/Debugging/QtdpPJT0">debugging</a>, etc. are available to various degrees.
