Nice solution! Is there a reason for the return before dirReduc(arr)? Just curious because I tried it without the return and it also worked.

I am wondering if this could be just sorted.slice(-1) without the [0]?

As I know, length is for string, but is a vector, that means dinamic array of strings. I used names.size()

Not a kata issue.

I think there is a typo, it should be: The round yellow light on top blinks to denote odd- (when lit) or even-numbered (when unlit) seconds (as written here: https://en.wikipedia.org/wiki/Mengenlehreuhr)
Please can you change it in the question?
Many thanks

Sorry, a bit confused, could someone explain how this code works - I don't understand how pop() works on an empty array? What exactly is being popped and pushed?

I used a Date object to convert the number of minutes to a properly formatted time string.
The Date constructor takes the number of milliseconds since the start of the epoch, see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/Date#Parameters

Minutes to milliseconds conversion
