## 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： var ourStorage = {
“桌子”：{

}，
“内阁”：{
“顶级抽屉”：{
“folder1”：“一个文件”，
“folder2”：“秘密”
}，
“底部抽屉”：“苏打水”
}
};
ourStorage.cabinet [“top drawer”]。folder2; //“秘密”
ourStorage.desk.drawer; //“订书机”
## Instructions
访问myStorage对象并将glove box属性的内容分配给gloveBoxContents变量。对于名称中包含空格的属性，请使用括号表示法。
## Tests
```yml
tests:
- text: gloveBoxContents应该等于“地图”
testString: 'assert(gloveBoxContents === "maps", "gloveBoxContents should equal "maps"");'
- text: 使用点和括号表示法访问myStorage
testString: 'assert(/=\s*myStorage\.car\.inside\[\s*("|")glove box\1\s*\]/g.test(code), "Use dot and bracket notation to access myStorage");'
```
