在for循环中调用异步函数

async function processItems() {
  for (const item of items) {
    await asyncFunction(item);
  }
}

function processItems() {
  const promises = items.map(asyncFunction);
  return Promise.all(promises);
}

function processItems() {
  const promises = items.reduce((accumulator, item) => {
    return [...accumulator, asyncFunction(item)];
  }, []);
  return Promise.all(promises);
}

async function processItems() {
  for (const item of items) {
    await asyncFunction(item);
  }
}
