Challenge: MVP Pattern

In this challenge, you have to implement the MVP pattern to solve the given problem.

We'll cover the following

Problem statement

In this challenge, you need to implement sending and displaying a sent email using the MVP pattern. You have already been given the dummy code for the classes you need to implement.

In the Model class should contain the following:

  • The properties: sender’s name, receiver’s name, and the email title.

  • The get and set functions to access and set the values of each property.

In the View class, you need to do the following:

  • Define the sendEmail function to send an email.

In the Presenter class, you need to do the following:

  • Define the setModel function that sets the model.

  • Define the getView function to return the view.

  • Define the sendEmail function that sets the properties of the email and displays the email information.

Input

The sendEmail function is called

Output

The information of the email is displayed

Sample input

var model   = new Model()
var view = new View()
var presenter = new Presenter(view)
presenter.setModel(model)
view.registerWith(presenter)
presenter.getView().sendEmail("Rachel", "Joey", "Rent Discussion")
presenter.getView().sendEmail("Monica", "Phoebe", "Smelly Cat Draft")

Sample output

"Email From: Joey To: Rachel Title: Rent Discussion"

"Email From: Phoebe To: Monica Title: Smelly Cat Draft"

        this.view = view;
        this.model = null;
    }
    setModel(model){
        //write code here
    }
    getView(){
       //write code here
    }
    sendEmail(to,fromWhom, emailTitle){
        //write your code here
    }
}
