# --description--

Inside your `allCategories` object, add a new key for the number `299` with a value of an empty object.

Inside that object, add a property with a key of `category` and a string value of `"Career Advice"`. Below that property, add another key called `className` with a string value of `"career"`.

# --hints--

Your `allCategories` object should have a `299` property.

```js
assert.property(allCategories, '299');
```

Your `299` value should be an object.

```js
assert.isObject(allCategories['299'])
```

Your `299` object should have a `category` property.

```js
assert.property(allCategories['299'], 'category');
```

Your `category` property should be set to the string `"Career Advice"`.

```js
assert.equal(allCategories["299"].category, 'Career Advice');
```

Your `299` object should have a `className` property.

```js
assert.property(allCategories['299'], 'className');
```

Your `className` property should be set to the string `"career"`.

```js
assert.equal(allCategories["299"].className, 'career');
```
