JavaScript Classes and Methods - Interactive Homework

In this notebook, you will learn about classes and methods in JavaScript. After the lesson, complete the tasks by editing the code cells.

What are Classes and Methods?

Class: A blueprint for creating objects with properties and methods.
Method: A function inside a class that defines an object’s behavior.

Example: Class for food

Below is an example of a JavaScript class for creating different foods. The class has:

A constructor to initialize properties (brand and model).
Two methods (displayInfo and start) to define behaviors.

%%js
// Fridge Mini-Game: Enhanced with scores and quality feedback
//place class + constructor here
class fridge {
  constructor() {
    // Array of items in the fridge with their scores
    this.fridgeItems = [ //Write in ten items found in a fridge and assign them a value of 1-10 (values can repeat)
      { name: "Piece of pizza", score: 10 },
      { name: "apple", score: 9 },
      { name: "cake", score: 7 },
      { name: "ice cream", score: 5 },
      { name: "milk", score: 4 },
      { name: "cheese", score: 3 },
      { name: "orange juice", score: 2 },
      { name: "orange", score: 1 },
      { name: "hot dog", score: 11 },
      { name: "chicken ", score: 6 } // Its more fun if it FUNNY
    ];
  }
  // Method to pick a random item from the fridge
  getRandom() {
    let random = Math.floor(Math.random() * this.fridgeItems.length);
    return this.fridgeItems[random];
  }
  // Method to classify the find based on its score
  classifyFind(score) { // Create an if -> return -> else -> return loop using youe scoring system to create an output of good, meh, bad
    if(score >= 9){
      return "good";
    }
    else if(score >= 5){
      return "meh";
    }
    else{
      return "bad";
    }
  }
  // Reference method to start the game (Some fill in the blank)
  start() {
    console.log("game started"); // Write a response
    const item = this.getRandom();
    console.log(`item is  ${item.name}`); //fill in the () with a phrase on the item and a reference to the item
    // Get feedback based on the item's score (unchanged you only need to fix the {} )
    // find and fix the misisng pieces
    const feedback = this.classifyFind(item.score);
    console.log(`It is ${feedback} Score: ${item.score}`);
  }
}
// Create an instance of the game  hint: const.
const fridgeGame = new fridge();
// Start the game by calling the play method hint .play
fridgeGame.start()
