Question

感谢您查看我的问题！我试图在codecademy中完成JavaScript课程，这让我很难过。我甚至无法在codecademy论坛中找到帮助。我想弄清楚为什么＆＃34; Bob Jones＆＃34;没有登录到控制台。任何帮助是极大的赞赏。这是我的代码：

var bob = {
    firstName: "Bob",
    lastName: "Jones",
    phoneNumber: "(650) 777-7777",
    email: "bob.jones@example.com"
};

var mary = {
    firstName: "Mary",
    lastName: "Johnson",
    phoneNumber: "(650) 888-8888",
    email: "mary.johnson@example.com"
};

var contacts = [bob, mary];

function printPerson(person) {
    console.log(person.firstName + " " + person.lastName);
};

function list() {
    var contactsLength = contacts.length;
    for (var i = 0; i < contactsLength; i++) {
        printPerson(contacts[i]);
    }
};

/*Create a search function
then call it passing "Jones"*/
function search(lastName){
    var contactsLength = contacts.Length;
    for(var i = 0; i<contactsLength; i++){
        if(lastName === contacts[i].lastName){
            printPerson(contacts[i]);
        }
    }
};
search("Jones");

问题是JavaScript区分大小写，数组长度在length属性下可用，而不是Length。

P.S。学会使用调试器。

Javascript codecademy 5.5函数不会返回正确的数据
