Im making an address book application using JavaScript (plus HTML and CSS). (Use plain JavaScript, no third party libraries!).

How can i make it with entries?

• I need help doing this:
  • Entries have the following fields: name, telephone number, email
  • Individual entries must be represented as an Entry object
  • The contact list must be represented as an array of Entry objects
  • The application must be shipped with some sample initial data (meaning, with a non-empty address book)
