Would it be this instead?

`for (let i = 0; i < coverOpts.length; i++)`

That makes more sense to me.

This `forEach` loops over the element in an array, so it makes sense to use the length of this array in your `for` loop version.

Looking at how my previous codes are written.

**From this:**

```auto
  function initCovers(coverOpts) {
    coverOpts.forEach(function (opts) {
      init(opts);
    });
  }

```

**To this?**

```auto
  function initCovers(coverOpts) {
    for(let i = 0; i < coverOpts.length; i++) {
      init(coverOpts[i]);
    }
  }

```

You tell us 🙂 Does the `for` loop work the same as the `forEach` loop? This should be pretty easy to test by running the code.

Everything works the same as it should.

It sounds like you could do with some refreshing your knowledge of how `for` loops work. I would recomend looking for a basic JS course. FCC of course offers one.
