Tests:

warmup

for
let sum1 = 0; for (let i = 0, len = array.length; i < len; i++) { sum1 += parseFloat(array[i]); }
for ... of
let sum2 = 0; for (const num of array) { sum2 += parseFloat(num); }
forEach
let sum3 = 0; array.forEach(num => { sum3 += parseFloat(num); });
map
let sum4 = 0; array.map(num => { sum4 += parseFloat(num); });
reduce
let sum5 = array.reduce((sum, num) => sum + parseFloat(num), 0);
while
let sum6 = 0; let i = 0; while (i < array.length) { sum6 += parseFloat(array[i]); i++; }
some
let sum7 = 0; array.some(num => { sum7 += parseFloat(num); });
