Needs random tests

Initial code is wrong (zero arguments???)

Could do with random tests.

typeof new Boolean() //=> 'object'

I think this could be it. And I was almost certain my function was handling booleans correctly. (A link to my already submitted solution which required some monkey-patching to handle that final test case: https://www.codewars.com/kata/reviews/582b19b73166eb10c60000db/groups/5865778602698cadf40006f4)

But this is interesting because typeof new Boolean() == 'object' whereas typeof Boolean() == 'boolean'. Definitely handy to know.

Per MDN:

The new operator creates an instance of a user-defined object type or of one of the built-in object types that has a constructor function.

@docgunthrop, I got that too :( Try handling only plain object and Array :)

// console
new Boolean()        //=> [Boolean: false]
new Boolean(false)   //=> [Boolean: false]
new Boolean(0)       //=> [Boolean: false]
new Boolean(null)    //=> [Boolean: false]
typeof new Boolean() //=> 'object'

Passing all but the final test case. Is the input for that {'bool': false} ?

I get the following result:

✘ Expected: { bool: [Boolean: false] }, instead got: {}

I'm not sure what the expected result is supposed to be, based on the formatting. Is it expecting {"bool":false} ? I'm asking because [Boolean: false] does not appear to be valid syntax for any value types in JavaScript. When I test for {"bool":false} in console, I get the same back (not an empty object literal as indicated by the kata's test results).

Thanks a bunch for this feedback. I made some additions that address these concerns.

👍

I've taken the liberty of fixing this.

Hope you don't mind.

Initial Setup function name is wrong.

Oh, it isn't in the docs. I learned it recently from someone else myself. :P

Awesome, I was looking for something like that. Must have missed it in the docs.

Thanks!
