Very large negative values are not necessary. See that an hourglass is made up of 7 digits. the sum of 'those' 7 digits can be minimum when each digit is itself minimum, i.e, -9. Hence, the minimum sum will be (7)x(-9), which equals -63. So, we can initialize minimum as -64

or in JS:
let max;
if (typeof max !== 'number' || sum > max) { max = sum }

you could actually initialize it with -63 ,would still work.
In JS, I used
let maxSum = Number.MIN_SAFE_INTEGER;
