Event Recommender System with Javascript

Projected Time

1-3 hours

Primary Goals

To build a modular system using Object Oriented Programming principles.

Overview

In this project, you'll build an EventRecommender System that will help you practice Object Oriented Programming using Javascript.

How to get Started

User Requirements

You need to build a program that lets users browse a list of events and save the ones they are interested in. For today's piece of the project, you'll write object-oriented JS code to manage users and events. In a later lesson, you'll add a UI for your users to use.

When you instantiate an EventRecommender object, you should be able to do the following:

• Users:
  • Add a new User to the System
  • Allow users to save events to a personal Events array
  • Delete a User from the System
• Event:
  • Add a new Event to the System
  • Delete an Event from the System
• Search:
  • Search for events by date
  • Search for events by category

Creating a plan of attack

Before you start coding, think about and write down the answers to these questions:

• What classes will you create?
• What properties should each class have? Think about: What properties are needed to complete the assignment? What other properties would be helpful to include as well?
• What methods should each class have?

You may change your answers as you write the code, but it's good to have a general plan worked out before you code.

Starter Code

Note:

• Create a JavaScript file for your class(es); it highly encouraged to make a User and Event class above and outside of your EventRecommender class.
• You will need to decide which arguments each function takes in.

Start with the following code:

class EventRecommender {
    constructor() {
    // All main properties should go here.
    
    this.events = [];
    this.users = [];
    
    }

    addEvent() {
    // Adds a new Event to the System
    }

    addUser() {
    // Adds a new User to the System
    }

    saveUserEvent(){
    // Allow users to save events to a personal Events array.
    }

    deleteUser() {
    // Deletes a User from the system
    }
   
    deleteEvent() {
    // Deletes the Event from the system
    }

    findEventsByDate(){
    // Returns all events on a given date
    }
    
    findEventsbyCategory(){
    // Returns all events in a given category
    }
}

Good luck!
