Thank you for your answer.

So I guess this is something that should be fixed by Kata authors.

Every time I submit my solution or even when I submit default/empty solution the test throws the error:

Error: Strings are not allowed.
Found 'global was reassigned'
   at dontTryAndCheat
        at Object.handleError
        at ContextifyScript.Script.runInThisContext
    at Object.exports.runInThisContext

Even the following code throws the error:

var helloWorld = function() {

}

Maybe the issue is that Babel transpiles the code with the string "use strict" that is being identified as "prohibited" string by the kata?

Could you please check if this is the case?

Hi @mattlub,

I can't pass the tests because of results that I get are seems to be better in all cases than expected test ones.

Could you please evaluate if my algorithm (written on JavaScript) is wrong or maybe there are kata tests or default algorithm that is not optimal?

Thank you in advance!
