The entire runtime API/ABI for Firefox OS is HTML5, so technically JavaScript is all you get. :)
It's possible however to compile other languages to JavaScript -- for instance C and C++ programs using the emscripten compiler < http://emscripten.org/>. Emscripten's output uses the 'asm.js' subset of JavaScript which Firefox optimizes particularly well in recent versions. Non-C/C++ languages that produce LLVM bitcode directly may also work with emscripten, as do languages like Lua that have a C-based runtime and don't require fancy JIT compilation tricks. However an interpreter running in the JavaScript VM may incur some overhead, so watch those constraints... (One of emscripten's main targets is C/C++/OpenGL game engines, which tend to be compiled to native code for iOS, Android, Windows, etc.) -- brion vibber (brion @ pobox.com / bvibber @ wikimedia.org) On Wed, Apr 9, 2014 at 10:47 AM, Bob Thulfram <[email protected]> wrote: > I've just been using JavaScript with Firefox OS but I recently saw a > book on Web Frameworks from Pragmatic called Seven Web Frameworks in > Seven Weeks: Adventures in Better Web Apps. > http://pragprog.com/book/7web/seven-web-frameworks-in-seven-weeks > > This book covers Ruby, JavaScript, Erlang, Haskell, and Clojure.
