I have never seen this in the work place. Why would anyone wrap default behavior into a function that has a similar name? This just adds a layer of confusion, no offense. One-lining an arrow function is fine, but breaking it out is more legible when staring at a codebase.

Edit: commented without seeing the problem has function maps(x) defined

There is no example of the tests being order dependent just that there are an equal number of open and closed parens.

But isn't that (the brackets being order-dependent) implied by daily life usage? Surely, if I wrote my first sentence in the following way instead:

But isn't that )the brackets being order-dependent( implied by daily life usage?

... wouldn't it make no sense at all?

There is absolutely no problem with the code examples in the Description; it just didn't show the edge cases yet (which is always a best practice to account for whenever necessary).

When calling an issue, please explain clearly how it's a kata issue and not a code issue. "I am failing tests" is not in and of itself an issue.

Closing.

Yes. Just do it ;-)

Same here. Last four test failed. But all seems ok. [edit] my bad - code is not right

I have the same problem too.

It seems '(' must before ')'.I realized it when I saw the others' solution

same problem. When is the issue going to be fixed?

how you do? i am also fails.but i just count of the ")"and "(".
