Script Preparation code:

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

Tests:

Math.max
return Math.max(...values.map(x => x.val));
Reduce with compare
return values.reduce((prev, curr) => { if (curr.val > prev) return curr.val; return prev; }, 0);
Reduce with max
return values.reduce((prev, curr) => { return Math.max(prev, curr.val); }, 0);
