About my code in Return Largest Numbers in Arrays

Just want to talk about my code on Return Largest Numbers in Arrays (that’s the challenge link). My code here is this:

const largestOfFour = (arr) => {
	return arr.map(num => Math.max(...num));

Code Explanation:

  • So this one-line return code that uses the map() function where it loops on the 4 arrays and then the constructor function num would return the maximum value of the arrays.

It passed on the code testing but I’m just wondering if there’s a loophole in my code?

What do you mean excatly with loophole?
As far as I can figure it out you followed the instructions and the requirment are meet.

I didn’t explain it probably, just like, I knew I met the requirements but I am confused if my solution would process a wrong output somewhere, referring it as a loophole…
