async function promiseAll(functions) {
  return new Promise((resolve, reject) => {
    const promisesCount = functions.length;
    const results = [];
    let resolvedCount = 0;
    let rejected = false;

    const handlePromise = async (func, index) => {
      try {
        const result = await func();
        if (!rejected) {
          results[index] = result;
          resolvedCount++;
          if (resolvedCount === promisesCount) {
            resolve(results);
          }
        }
      } catch (error) {
        if (!rejected) {
          rejected = true;
          reject(error);
        }
      }
    };

    functions.forEach((func, index) => {
      handlePromise(func, index);
    });
  });
}
