here is my code:

// An Email Simulation /* create your email class here */ class Email { constructor(fromAddress, emailContents) { this.fromAddress = fromAddress; this.emailContents = emailContents; this.hasBeenRead = false; this.isSpam = false; } markAsRead() { this.hasBeenRead = true; } markAsSpam() { this.isSpam = true; } } const inbox = []; function addEmail(contents, address) { const email = new Email(address, contents); inbox.push(email); } function getCount() { return inbox.length; } function getEmail(index) { const email = inbox[index]; email.markAsRead(); return email.emailContents; } function getUnreadEmails() { return inbox.filter(email => !email.hasBeenRead); } function getSpamEmails() { return inbox.filter(email => email.isSpam); } function deleteEmail(index) { inbox.splice(index, 1); } let userChoice = ""; while (userChoice !== "7") { userChoice = prompt( "What would you like to do: 1. Read email 2. Mark spam 3. Send email 4. Delete email 5. View spam emails 6. View unread emails 7. quit?" ); if (userChoice === "1") { const index = prompt(`Enter index of email (0-${getCount() - 1}):`); console.log(getEmail(index)); } else if (userChoice === "2") { const index = prompt(`Enter index of email (0-${getCount() - 1}):`); inbox[index].markAsSpam(); console.log(`Email at index ${index} marked as spam.`); } else if (userChoice === "3") { const contents = prompt("Enter email contents:"); const address = prompt("Enter sender email address:"); addEmail(contents, address); console.log("Email added to inbox."); } else if (userChoice === "4") { const index = prompt(`Enter index of email (0-${getCount() - 1}):`); deleteEmail(index); console.log(`Email at index ${index} deleted from inbox.`); } else if (userChoice === "5") { console.log("Spam emails:"); console.log(getSpamEmails()); } else if (userChoice === "6") { console.log("Unread emails:"); console.log(getUnreadEmails()); } else if (userChoice === "7") { console.log("Goodbye"); } else { console.log("Oops - incorrect input"); } }

lecturers review: You have not instantiated your Class so your program has nothing to work with. You need to create a couple of Email instances and this will be your objects that you will be working with.

Please help me fix my code to the lecturers comments
