일련의 약속을 순서대로 실행하고 거부를 처리하는 방법은 무엇입니까?

function sequence(arr) {
  const index = 0;

  function next() {
    if (index < arr.length) {
      arr[index]().then(next).catch(reject);
      index++;
    }
  }
  next();
}

function sequence(arr) {
  return arr.reduce((p, item) => {
    return p.then(() => item()); // Assuming each element is a promise-returning function
  }, Promise.resolve());
}

function sequence(arr) {
  return Promise.mapSeries(arr, item => item());
}

async function sequence(arr) {
  const results = [];
  for (let item of arr) {
    results.push(await item());
  }
  return results;
}

import { sequence } from 'spex';

function sequence(nextPromise) {
  // while nextPromise() creates and returns another promise, continue resolving it;
}
