The description says the name of the array is partyAges, but the example and actual code use the array party_ages.

The kata doesn't describe what the code is supposed to do, so it's unclear what we need to fix in it.

• not enough tests
• needs random tests
• specs of the fill value aren't sufficient: what if fill is a list? a list of lists? So just say that it will be a value or a string

@StefanPochmann: it would be nice to implement that, yes. That would require a modification of the description too, though.

Basically it doesnt describe what the original problem is so how we fix?

We can make sure the tests pass but that doesnt really demonstrate anything useful.

For better task understanding you could make better code quality/readability with some meaningful function names instead of just anonymous functions.
Without doing final attempt to task, there is hard to understand that code need to handle integer convertation to octal number too.

Java Translation kumited! Please Accept :D

CoffeeScript Translation kumited! Please Accept :D

Hope it resembles your original intention

The base 2 (binary) or 8 (octal) is unrelated to array index value so why call the index base (??) Seems a misleading parameter name to me.

I translated this kata into JS, but it should be renamed. Is there any possibility to do it?
