Jack - Making programming playful

Jack is a new language in development that gets translated to pure JavaScript and runs on top of nodeJS.


  • Be Simple! This is very important
  • Be fun! Otherwise, what's the point
  • Be productive! We can only really make time for this is something good comes out of it.

Technical ideas

  • Compile cleanly down to JavaScript.
  • Use real prototypical inheritance, not the hacked version that made it into JavaScript.
  • Use real whitespace rules and get rid of those semicolons and braces.
  • Create a clean syntax for defining variables, objects and functions/blocks. That should be all that's needed.
  • Not allow fuzzy things like implicit globals and type coercion.
  • Implement a real compiler with some static analysis, not just regular expression hacks.
  • Unit tests all the way!
