===== 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 items = Array.from(promises);
    const results = new Array(items.length);
    let pending = items.length;

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

    items.forEach((p, idx) => {
      Promise.resolve(p)
        .then(value => {
          results[idx] = value;
          pending -= 1;
          if (pending === 0) resolve(results);
        })
        .catch(err => reject(err));
    });
  });
}

module.exports = { promiseAll };
```
