## Description
<section id='description'>
The sub-properties of objects can be accessed by chaining together the dot or bracket notation.
Here is a nested object:
<blockquote>var ourStorage = {<br>&nbsp;&nbsp;"desk": {<br>&nbsp;&nbsp;&nbsp;&nbsp;"drawer": "stapler"<br>&nbsp;&nbsp;},<br>&nbsp;&nbsp;"cabinet": {<br>&nbsp;&nbsp;&nbsp;&nbsp;"top drawer": { <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"folder1": "a file",<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"folder2": "secrets"<br>&nbsp;&nbsp;&nbsp;&nbsp;},<br>&nbsp;&nbsp;&nbsp;&nbsp;"bottom drawer": "soda"<br>&nbsp;&nbsp;}<br>};<br>ourStorage.cabinet["top drawer"].folder2; // "secrets"<br>ourStorage.desk.drawer; // "stapler"</blockquote>
</section>
## Instructions
<section id='instructions'>
Access the <code>myStorage</code> object and assign the contents of the <code>glove box</code> property to the <code>gloveBoxContents</code> variable. Use bracket notation for properties with a space in their name.
</section>
## Tests
<section id='tests'>
```yml
tests:
- text: <code>gloveBoxContents</code> should equal "maps"
testString: assert(gloveBoxContents === "maps", '<code>gloveBoxContents</code> should equal "maps"');
- text: Use dot and bracket notation to access <code>myStorage</code>
testString: assert(/=\s*myStorage\.car\.inside\[\s*("|')glove box\1\s*\]/g.test(code), 'Use dot and bracket notation to access <code>myStorage</code>');
```
</section>
## Challenge Seed
<section id='challengeSeed'>
<div id='js-seed'>
```js
// Setup
var myStorage = {
"car": {
"inside": {
"glove box": "maps",
"passenger seat": "crumbs"
},
"outside": {
"trunk": "jack"
}
}
};
var gloveBoxContents = undefined; // Change this line
```
</div>
### After Test
<div id='js-teardown'>
```js
(function(x) {
if(typeof x != 'undefined') {
return "gloveBoxContents = " + x;
}
return "gloveBoxContents is undefined";
})(gloveBoxContents);
```
</div>
</section>
## Solution
<section id='solution'>
```js
var myStorage = {
"car":{
"inside":{
"glove box":"maps",
"passenger seat":"crumbs"
},
"outside":{
"trunk":"jack"
}
}
};
var gloveBoxContents = myStorage.car.inside["glove box"];
```
