var values = new Array(5000);

for (let i = 0; i < values.length; ++i) {
    values[i] = i % 20;
}

Tests:

Math.max
return Math.max(...values);
Reduce
return values.reduce((prev, curr) => { if (curr > prev) return curr; return prev; }, 0);
for element of array
let biggest = values[0]; for (let value of values) { if (value > biggest) biggest = value; }; return biggest;
