Script Preparation code:

var arr = [];
var max = -Infinity;
for (i = 0; i < 4096; i++) { 
  arr.push(Math.random() * i);
}

Tests:

Math.max.apply
max = Math.max.apply(Math, arr);
Math.max with spread
max = Math.max(...arr);
basic for loop
for (let i = 0; i < arr.length; i++) { if (arr[i] > max) { max = arr[i]; } }
for loop length caching
for (let i = 0, len = arr.length; i < len; i++) { if (arr[i] > max) { max = arr[i]; } }
for loop reverse
for (let i = arr.length - 1; i >= 0; i--) { if (arr[i] > max) { max = arr[i]; } }
for-of loop
for (const value of arr) { if (value > max) { max = value; } }
