added all 3 to JavaScript

@hpr that will only seem to work until it breaks terribly one day. JavaScript is a concurrent, non-blocking language. One script can modify a global variable just before or after another script was reading it. So you enter into all kinds of race condition headaches by sharing state with global variables.

this is a very elegant solution

Non-numeric inputs have been removed from JS version.

Moved reference solution function to the describe block scope, should be ok now

reference solution is fixed

I really don't remember what this was about, but are you referring to this?

Note: This kata uses the non-padding version ("=" is not added to the end).

Because I think that must have been added to the description after I had written the comment.

This does not confront to standards in 2023 ~!

oh, sorry, I didn't see that part of the description... 'x) (I just completed the kaata again in JS, in "TDD-only" mode). Let's remove that.

I can kinda see how has always seems to be used on a base object while having is used further down an expression chain (although this seems to be a distinction without any meaningful difference).

But with is brought up in the description without there being any significant difference between with and having:

// can define properties on nested items
jane.has(1).head.having(2).eyes.each( eye => being_the.color.blue.with(1).pupil.being_the.color.black )

What makes with(1).pupil the correct syntax for that expression vs. having(1).pupil? As far as I can tell they mean exactly the same thing.

I don't see how any of this is an issue.

• has is instance based
• nobody ever talked about with
• having is... what it is (both instance and "hack" based. Both tested)... The setup of the kata is rather unfortunate, involving a lot of hacks.

at most a suggestion, since it's more about adding specs than pointing an actual problem.

closing

beautiful code!

Seems so. But the problem is that test accepts your code now. And numbers are mentioned only in description.

The kata was probably changed to add numbers in addition to alphabetic characters.
