## Description
<section id='description'> <code>0</code>使用之前构建的Person构造函数创建文档实例。将具有字段名称，年龄和favoriteFoods的对象传递给构造函数。它们的类型必须符合Person Schema中的类型。然后在返回的文档实例上调用方法document.save（）。使用Node约定传递回调。这是一种常见模式，以下所有CRUD方法都将这样的回调函数作为最后一个参数。 
<code>/* Example */</code> 
<code>// ...</code> 
<code>person.save(function(err, data) {</code> 
<code>// ...do your stuff here...</code> 
<code>});</code>
