Getting the min and max value in JavaScript, but from a 2D array

Question

I know this gets asked again and again but hear me out - this question is slightly different.

I can get a max or min from a 1D array like this:

var          


        

Answer 1

The first answer is not correct!!!

let arr = [[1, 112.0],[2,5.12],[3,113.1],[4,33.6],[5,85.9],[6,219.9]];
let values = Array.concat.apply([],arr);
let max = Math.max(...values);
let min = Math.min(...values);
console.log(arr)
console.log(min)//1
console.log(max)//219.9
console.log(values)//[ 1, 112, 2, 5.12, 3, 113.1, 4, 33.6, 5, 85.9, 6, 219.9 ]
