for let	232046.8 Ops/sec

Script Preparation code:

const testArray = [];
for (let i = 0; i < 1000; i++) {
    testArray.push(i);
}

function executitionTask(elem) {
    return elem + 10 - 100;
}

Tests:

for of
const testArray = []; for (let i = 0; i < 1000; i++) { testArray.push(i); } function executitionTask(elem) { return elem + 10 - 100; } for (const i of testArray) { executitionTask(i); }
for let
const testArray = []; for (let i = 0; i < 1000; i++) { testArray.push(i); } function executitionTask(elem) { return elem + 10 - 100; } for (let y = 0, len = testArray.length; i < len; i++) { executitionTask(i); }
