Discussion on: Limit concurrent asynchronous calls

[Kushan Joshi]

Great article! Some minor improvements.

const asyncLimit = (fn, n) => {
  const pendingPromises = new Set();
  return async function(...args) {
    while (pendingPromises.size >= n) {
      await Promise.race(pendingPromises);
    }

    const p = fn.apply(this, args);
    const r = p.catch(() => {});
    pendingPromises.add(r);
    await r;
    pendingPromises.delete(r);
    return p;
  };
};
