There's a trade-off here, which for a 6 kyu could well fall in the direction of conciseness.

Let's close it.

(commenting here because i upgraded to Node 18 + chai)

is this still relevant ? the author's solution is probably buried somewhere in the Solutions page at this point. are you arguing that { 3:3 } should be written { '3':3 } in the sample tests ? that makes the object literals more verbose for no good reason, in my opinion. it's maybe confusing for beginners, but learning that all object properties are (implictely coerced to) strings has to come at one point or another

done and done

Fixed (along with C translation warning) in this fork. Please approve.

Nice

Great 8kyu exercise, link was useful to get a larger scope of the function.

Who needed to read that long document?

I've seen your code in javascript and it is not right, not a kata issue. Print the input, use fun.toString() to see what the code of the function is.

returns true if the function in the params returns true for every element in the sequence

Your code doesn't do that.

That depends on the function. In which language?

if this happens, just return an empty list because you can't create proper cascading subsets.
