## Description
|
||
|
|
<section id="description">我们的联系人列表中有一组代表不同人的对象。已经为您预先编写了一个以<code>name</code>和属性（ <code>prop</code> ）作为参数的<code>lookUpProfile</code>函数。该函数应检查<code>name</code>是否是实际联系人的<code>firstName</code> ，并且给定属性（ <code>prop</code> ）是该联系人的属性。如果两者都为真，则返回该属性的“值”。如果<code>name</code>与任何联系人不对应，则返回<code>"No such contact"</code>如果<code>prop</code>不符合找到匹配<code>name</code>的联系人的任何有效属性，则返回<code>"No such property"</code> </section>
