## 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 >
