Run results for:
array math.max vs for loop
compare finding the maximum value with math.max using .apply & using the spread (...) operator, vs a basic for loop with an if statement, & finally a basic foor loop using length caching

Script Preparation code:
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]; } }
