# --description--

The `keywords` field is where you can describe your project using related keywords. Here's an example:

```json
"keywords": [ "descriptive", "related", "words" ],
```

As you can see, this field is structured as an array of double-quoted strings.

# --instructions--

Add an array of suitable strings to the `keywords` field in the package.json file of your project.

One of the keywords should be "freecodecamp".

# --hints--

package.json should have a valid "keywords" key

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert(packJson.keywords, '"keywords" is missing');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

"keywords" field should be an Array

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.isArray(packJson.keywords, '"keywords" is not an array');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

"keywords" should include "freecodecamp"

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.include(
        packJson.keywords,
        'freecodecamp',
        '"keywords" does not include "freecodecamp"'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
