# --description--

`parseCatalog` currently returns an empty array. To fill it, add a `for` loop inside the function that iterates over `rawCards`. Inside the loop, call `parseCard` on each element and push the result into `catalog`.

# --hints--

`parseCatalog(rawCatalogCards).length` should be `19`.

```js
assert.strictEqual(parseCatalog(rawCatalogCards).length, 19);
```

`parseCatalog` should use a `for` loop to iterate over `rawCards`.

```js
assert.match(parseCatalog.toString(), /for\s*\(\s*(var|let)\s+(\w+)\s*=\s*0\s*;\s*\2\s*<\s*rawCards\s*\.\s*length\s*;\s*\2\+\+\s*\)\s*\{/);
```

You should call `parseCard` inside the loop.

```js
assert.match(parseCatalog.toString(), /parseCard\s*\(/);
```
