Test name	Executions per second
For loop	1.5 Ops/sec
Yield	2.2 Ops/sec

Script Preparation code:

function chunkArray(arr, chunkSize) {
    const result = [];

    for (let i = 0; i < arr.length; i += chunkSize) {
        const chunk = arr.slice(i, i + chunkSize);
        result.push(chunk);
    }

    return result;
}

Tests:

For loop
function task(data) { return new Promise((resolve, reject) => { const results = data.reduce((acc, curr) => acc + curr, 0) resolve(results) }) } const datasets = [...Array(5_000_000).keys()] for (chunk of chunkArray(datasets, 10000)) { task(chunk).then( (res) => { // } ) }
Yield
function* task(data) { return new Promise((resolve, reject) => { const results = data.reduce((acc, curr) => acc + curr, 0) resolve(results) }) } function* process(data) { for (chunk of chunkArray(data, 10000)) { yield task(chunk) } } const datasets = [...Array(5_000_000).keys()] for (data of process(datasets)) { const resp = data.next().value resp.then((res) => { // }) }
