I love it! Beautiful, even if it's in the same complexity class ;)

@nuzyly Yes, you are completely correct.

The intention is better readable that way, but a comment would suit it better, I'd say.

Very nice, but let me ask:

• what do you match and remove with '[.]\w+'?
• Why do you remove a trailing slash from the URL with '/$', at the end of the regex, when you call split("/") on the returned String anyway?

PS: If the code would be used on a lot of URLs, it would save some load to call replace("-", " ") with the return statement, like so: return item.replace("-", " ");
and split the stream with "-".

The (Java) Kata provides an array of Objects, but does only provide Strings in it. This leads to a lot of solutions, that skip type checking and casting (if necessary) and thus reinforces bad coding habits.

So is it clever or best practice? :)

I am new to JavaScript, so I am wondering if JavaScript does enforce semicola, or if the author of this solution was just lazy and the interpreter forgiving?

Without more information I guess it is hard to give any advise other than, insert some debug lines into your code.

• Print the digits with their corresponding powers.
• Print the sum.
• Print the quotion and the remainder next to each other.

In your first conditional
do{
n=n/10;
i++;
} while (n>0);

n is set to 0, as soon as it's done. Thus, when you want to extract the digits from n in your second do-while loop, you always get 0, trough the first and only iteration.

It is so interesting how many different ways there are to write code achieving the same goal, I really missed that in university. Great platform.

Your solution is heavy on computational demand, scaling with n. I have found a solution scaling with the pattern length. Compare it if you are interested. :)
