## Description
<section id="description">可以通过将点或括号表示法链接在一起来访问对象的子属性。这是一个嵌套对象： <blockquote> var ourStorage = { <br> “桌子”：{ <br> “抽屉”：“订书机” <br> }， <br> “内阁”：{ <br> “顶级抽屉”：{ <br> “folder1”：“一个文件”， <br> “folder2”：“秘密” <br> }， <br> “底部抽屉”：“苏打水” <br> } <br> }; <br> ourStorage.cabinet [“top drawer”]。folder2; //“秘密” <br> ourStorage.desk.drawer; //“订书机” </blockquote></section>

## Instructions
<section id="instructions">访问<code>myStorage</code>对象并将<code>glove box</code>属性的内容分配给<code>gloveBoxContents</code>变量。对于名称中包含空格的属性，请使用括号表示法。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>gloveBoxContents</code>应该等于“地图”
    testString: assert(gloveBoxContents === "maps");
  - text: 使用点和括号表示法访问<code>myStorage</code>
    testString: assert(/=\s*myStorage\.car\.inside\[\s*("|')glove box\1\s*\]/g.test(code));

```
