Objective: Create a digital contact book that allows users to manage their contacts.

Requirements:

Contact Object: Students should define a JavaScript object template for a contact, with properties like

$,$ and

Contact List: Implement an array or another data structure to store multiple contact objects. This will serve

as the contact list in the contact book.

Functionality:

a$.$ Add Contacts: Students should be able to add new contacts to the contact list. When adding a contact,

the user should provide the contact's name, phone number, and email address.

b$.$ Edit Contacts: Allow users to edit the information of existing contacts. They should be able to update the

name, phone number, and email address for a contact.

c$.$ Search Contacts: Implement a search feature that allows users to find a specific contact by entering the

contact's name or other unique identifier. The application should then display the contact's information if

found.

d$.$ Display All Contacts: Provide an option to display all contacts in the contact book. This could be in the

form of a list, table, or any other user$-$friendly format.

User Interface: Create a simple user interface $($UI$)$ for interacting with the contact book. This could be a

web page with input fields for adding and editing contacts, a search bar, and a display area for showing

contact details.

Validation: Implement basic input validation to ensure that the user provides valid data $($e$.$g$.,$ a valid email

address format$).$

Error Handling: Handle errors gracefully. For example, if a user searches for a contact that doesn't exist,

display a message informing them that the contact was not found.

Optional Features: Students can add optional features like deleting contacts, sorting contacts by name, or

exporting the contact list to a file.
