===== ISTEM =====
Solve the following programming task.

TASK: Custom Promise.all (promiseAll)

Write a function 'promiseAll(promises)' that mimics the behaviour of the native Promise.all. If all promises fulfil it must resolve with an ordered array of results; if any rejects it must reject immediately with that error.

STARTER CODE (javascript):
function promiseAll(promises) {
  // Write your code here
}

module.exports = { promiseAll };


RULES:
- Keep the function name and signature EXACTLY as given.
- Return working code only. No explanations.
- Put the code in a single ``` block.
- Try to solve it first. If you genuinely cannot, write only this single
  line instead of producing faulty code: CANNOT_SOLVE

===== HAM YANIT =====
```javascript
function promiseAll(promises) {
  return new Promise((resolve, reject) => {
    const results = [];
    let completed = 0;
    const total = promises.length;

    if (total === 0) {
      resolve([]);
      return;
    }

    promises.forEach((promise, index) => {
      Promise.resolve(promise)
        .then((value) => {
          results[index] = value;
          completed += 1;
          if (completed === total) {
            resolve(results);
          }
        })
        .catch((error) => {
          reject(error);
        });
    });
  });
}

module.exports = { promiseAll };
