console.log(twice(ten()));

API

jalosi.compile(scripts, imports, options);

Compiles an array of scripts together, but doesn't execute the code. (The scripts parameter can also be a single string.) If options.sandbox is truthy then only imports are made accesible to the script. Otherwise, everything from the global scope is included. (Excluding properties already defined by the imports object.) Returns an anonymous function.

jalosi.run(scripts, imports, options);

Invokes jalosi.compile, then runs the code. Returns whatever is returned by the combined scripts.

jalosi.defer(files, imports, options);

Same as jalosi.compile, but reads the scripts from an array of files instead. (The files parameter can also be a single string.) If options.path is set, all files will be loaded from the directory that it points to. Returns an anonymous function.

jalosi.load(files, imports, options);

Invokes jalosi.defer, then runs the code. Returns whatever is returned by the combined scripts.

jalosi(files, imports, options);

Alias for jalosi.load.

jalosi.cache;

Reference to Jalosi's file cache. (Useful for diagnostics.)
