Basic Algorithm Scripting - Return Largest Numbers in Arrays

Code Feedback
1

Sorry, a lazy JS beginner coder here. Could this solution fail any test, even those not included in the algo checks?

function largestOfFour(arr) {
  return (arr.length === 1) ? [Math.max(...arr[0])] : arr.map(innerArr => Math.max(...innerArr))
}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

console.log(largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]))

Could you clarify what you mean by “any test”?

3

I meant that, was I just lucky it passed all the tests for that exercise or the code is robust to work in any case.

i think the problem set is simple and there is no chance your code will fail some other unforeseen input. (well unless you get an empty array? but maybe that won’t be a problem)

Thanks. Tried now and it returned an empty array as I expected it.
