Find max value comparing multiple arrays for each index

Question

I\'m trying to find a method to find the max value comparing multiple(unknown number, but same length) arrays for each observation in the arrays, returning an array with the max

Answer 1

Here's a short and sweet version:

var A = [[2.2, 3.3, 1.3], [1.2, 5.3, 2.2], [0.3, 2.2, 5.2]];

var maxA = A.map(a => Math.max.apply(null, a));
