HEY THERE!

The BattleScript compiler is written in TypeScript so it can be executed anywhere JavaScript can run (such as in your browser). Your BattleScript code is compiled to the JSON-based AST format, (or the optional binary format found in the download section) by the compiler running in your browser. No internet connection is required to compile your scripts. You can also use the compiler in your own projects or download your own version for use in the command line. NPM Package: @irrelon/battlescript
