Promise 수가 많은 `Promise.all`을 사용할 때 메모리 소비를 효율적으로 관리하는 방법은 무엇입니까?

function mapConcurrent(items, maxConcurrent, fn) {
    // Limit concurrent operations to `maxConcurrent`
    let inFlightCntr = 0;

    return new Promise((resolve, reject) => {
        function runNext() {
            let i = index;
            let prom = fn(items[index], index++).then(...);
            inFlightCntr++;
            prom.finally(() => { inFlightCntr--; });
            prom.then(...); // Run resolve/reject based on returned promise
        }

        function run() {
            // Process items while count is below the limit
            while (inFlightCntr < maxConcurrent && index < items.length) {
                runNext();
            }

            // Resolve or reject parent promise based on completion
        }

        run();
    });
}

const p = backgroundScheduler.getClanProfile(clanTags[i], true).then(data => {
    return 0;     // Replace resolved value to promote garbage collection
});
promiseArray.push(p);
