# --description--

Your loop now needs a proper iterator. The <dfn>iterator</dfn> is a variable you can declare specifically in your `for` loop to control how the loop iterates or goes through your logic.

It is a common convention to use `i` as your iterator variable in a loop. A `for` loop allows you to declare this in the parentheses `()`. For example, here is a `for` loop that declares an `index` variable and assigns it the value `100`.

```js
for (let index = 100; "second"; "third") {

}
```

Replace the string `"iterator"` with a `let` declaration for the variable `i`. Assign it the value `0` to start. This will give the `i` variable the value `0` the **first time** your loop runs.

# --hints--

You should use `let` to declare an `i` variable.

```js
assert.match(__helpers.removeJSComments(code), /let\s+i/);
```

You should assign `0` to your `i` variable.

```js
assert.match(__helpers.removeJSComments(code), /let\s+i\s*=\s*0/);
```

Your `for` loop should start an `i` iterator at `0`.

```js
assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*0/);
```
