--description--

我们有一个对象数组,里面存储着通讯录。

函数lookUp有两个预定义参数:firstName值和prop属性 。

函数将会检查通讯录中是否存在一个与传入的firstName相同的联系人。如果存在,那么还需要检查对应的联系人中是否存在prop属性。

如果它们都存在,函数返回prop属性对应的值。

如果firstName值不存在,返回"No such contact"

如果prop属性不存在,返回"No such property"

--hints--

"Kristian", "lastName"应该返回 "Vos"

assert(lookUpProfile('Kristian', 'lastName') === 'Vos');

"Sherlock", "likes"应该返回 ["Intriguing Cases", "Violin"]

assert.deepEqual(lookUpProfile('Sherlock', 'likes'), [
  'Intriguing Cases',
  'Violin'
]);

"Harry","likes"应该返回 an array。

assert(typeof lookUpProfile('Harry', 'likes') === 'object');

"Bob", "number"应该返回 "No such contact"。

assert(lookUpProfile('Bob', 'number') === 'No such contact');

"Bob", "potato"应该返回 "No such contact"。

assert(lookUpProfile('Bob', 'potato') === 'No such contact');

"Akira", "address"应该返回 "No such property"。

assert(lookUpProfile('Akira', 'address') === 'No such property');
