Script Preparation code:

var array = [...Array(100000)].map(() => ({
    label: Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, 10),
    value: Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, 10)
}))

Tests:

for
for (var i = 0, n = array.length; i < n; i++) { array[i]; }
foreach
array.forEach(function(i) { array[i]; });
for..of
for (var i of array) { array[i]; }
