In JavaScript all the Random test gives me the next error:

   at simplify 
    at Test.it._ 
    at begin 
    at Object.it
    at Test.describe._
    at /runner/frameworks/javascript/cw-2.js:159:11
    at Promise._execute
    at Promise._resolveFromExecutor
    at new Promise
    at Object.describe
`            at Object.handleError
`        at ContextifyScript.Script.runInThisContext 
`    at Object.exports.runInThisContext`
    
  The regular tests work fine and tyring one of the random the algorithm also work... So it must be something about the random tests generator.

How do I help translating existing katas to other languages?

I can't run tests (javascript). I keep getting "Test didn't pass: Unknown error". Submmit works.
