# --description--

If the property name (key) of an object has a space in it, you will need to use single or double quotes around the name. 

Here is an example of an object with a property name that has a space:

```js
const spaceObj = {
  "Space Name": "Kirk",
};
```

If you tried to write a key without the quotes, it would throw an error:

```js
const spaceObj = {
  // Throws an error
  Space Name: "Kirk",
}; 

```

Add a new property with a key of `"Number of legs"` and value of `4` to the `cat` object.

Open up the console to see the output.

# --hints--

Your `cat` object should have a key called `"Number of legs"`.

```js
assert.property(cat, "Number of legs");
```

Your `cat` object should have a `"Number of legs"` property with a value of `4`.

```js
assert.propertyVal(cat, "Number of legs", 4);
```

Your `cat` object should have two properties.

```js
assert.lengthOf(Object.keys(cat), 2);
```
