var arr = [];
var max = -Infinity;
for (i = 0; i < 1000; 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];
      }
    }
