Script Preparation code:

var values = new Array(5000)

for (let i = 0; i < values.length; ++i) {
    values[i] = i % 20
}

const findMax = (arr) => {
    let max = -Number.Infinity
    for (let n = 0; n < arr.length; n++) {
        if (arr[n] > max) max = arr[n]
    }
    return max
}

Tests:

Math.max
return Math.max(...values)
Reduce
return findMax(values)
