Script Preparation code:

for(let i=0; i<5_000; i++) {
    all_digits.push(Math.floor(Number.MAX_SAFE_INTEGER * Math.random()).toString())
}

Tests:

for loop
for(let digits of all_digits) { let sum = 0; for (const digit of digits) { sum += +digit; } }
Array.prototype.reduce.call
for(let digits of all_digits) { let sum = 0; sum = Array.prototype.reduce.call(digits, (prev, curr) => prev + +curr, 0); }
Array.prototype.reduce.apply
for(let digits of all_digits) { let sum = 0; sum = Array.prototype.reduce.apply(digits, [(prev, curr) => prev + +curr, 0]); }
Array.prototype.forEach
for(let digits of all_digits) { let sum = 0; Array.prototype.forEach.apply(digits, [(i) => sum += +i]); }
.split.reduce
for(let digits of all_digits) { let sum = 0; sum = digits.split('').reduce((prev, curr) => prev + +curr, 0); }
.split.forEach
for(let digits of all_digits) { let sum = 0; digits.split('').forEach((i) => sum += +i); }
