Use console.log() to print your answer before returning

When an array in the array is null or empty, the method should return 0 too!

You're trying to read the length of null, that's what the error says. You have to check if it is an array first.

I really have no clue but I get the results below.
I thought if you get all the assertions it's a full pass if someone could explain I would love it.
I'm defintely trying to learn.

Test Passed: Value == 0 (<---Obviously just one of the passed tests but right below it is the error)

In JavaScript I just floored seconds and it worked without any rounding. Had frustrated experience because of this "round it to nearest second".
After reading issues section I confirmed what I suspected, author derped a bit here and refused to accept that.
Some of the tests are mathematically incorrect.
Edit: NVM, rounding down is not rounding, it is flooring.

For the race(80, 100, 40) I continue to get [1, 59, 59] instead of [2, 0, 0]. I'm using Javascript.
If I use round in some places it works but then the other tests break.
Not looking for the answer but I'm so close.
