Script Preparation code:

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);
Reduce Max.max
return values.reduce((prev, curr) => Math.max(prev, curr), 0);
for of
let mx = values[0]; for (const x of values) { if (mx < x) { mx = x; } } return mx;
for
let mx = values[0]; for (let i = 1; i < values.length; ++i) { if (values[i] > mx) { mx = values[i]; } } return mx;
for Math.max
let mx = values[0]; for (let i = 1; i < values.length; ++i) { mx = Math.max(values[i], mx); } return mx;
