Script Preparation code:

var values = new Array(10000);
for (var i = 0; i < values.length; i++) values[i]=i;

Tests:

foreach
var sum = 0; values.forEach(v => sum += v );
map
var sum = 0; values.map(v => sum += v );
for of transpiled
var sum = 0; for (var _i = 0, values_1 = values; _i < values_1.length; _i++) { var v = values_1[_i]; sum += v; }
reduce
var sum = values.reduce((s,v) => sum += v, 0);
for of
var sum = 0; for (var v of values) sum += v;
