Hello, I have written my random bear generator but for some reason the code isn't running in my command terminal. Please have a look at it and let me know what I am missing. I followed my teachers instructors and lectures, but it doesn't run on another compiler either. class Bear { constructor(type, color, weight, favoriteFood) { this.type = type; this.color = color; this.weight = weight; this.favoriteFood = favoriteFood; if (this.weight === 700 || this.type === "Little Bear" || this.type === "Baby Bear") { this.isAggressive = false; } else if (this.weight === 1200 || this.type === "Papa Bear" || this.type === "Black Bear") { this.isAggressive = true; } else { this.isAggressive = Math.random() < 0.5; } if (this.type === "Winnie the Pooh Bear" && this.favoriteFood !== "Honey") { throw new Error("Winnie the Pooh Bear must have Honey as his favorite food."); } } } class BearGenerator { get types() { return [ "Winnie the Pooh Bear", "Yogi Bear", "Boo-boo Bear", "Paddington Bear", "Mama Bear", "Papa Bear", "Baby Bear", "Little Bear", "Teddy Bear", "Smokey Bear", ]; } get colors() { return [ "Red", "Blue", "White", "Indigo", "Green", "Teal", "Fuchsia", "Brown", "Violet", "Black", ]; } get foods() { return [ "Honey", "Pizza", "Burger", "Burrito", "Wings", "Spaghetti", "Steak", ]; } createRandomBear() { const type = this.types[Math.floor(Math.random() * this.types.length)]; const color = this.colors[Math.floor(Math.random() * this.colors.length)]; const weight = Math.floor(Math.random() * 1250) + 250; const favoriteFood = this.foods[Math.floor(Math.random() * this.foods.length)]; return new Bear(type, color, weight, favoriteFood); } } class DataProcessor { constructor(data) { this.data = data; } getStatsFor(valuesArray, property) { const stats = {}; for (const value of valuesArray) { stats[value] = 0; } for (const bear of this.data) { stats[bear[property]] += 1; } for (const value of valuesArray) { stats[value] = (stats[value] / this.data.length) * 100; } return stats; } } function randomBears(numberOfBears) { const bearGenerator = new BearGenerator(); const bears = []; for (let i = 0; i < numberOfBears; i++) { bears.push(bearGenerator.createRandomBear()); } const dataProcessor = new DataProcessor(bears); console.log("Favorite Food Stats:"); console.log(dataProcessor.getStatsFor(bearGenerator.foods, "favoriteFood")); console.log("Type Stats:"); console.log(dataProcessor.getStatsFor(bearGenerator.types, "type")); console.log("Color Stats:"); console.log(dataProcessor.getStatsFor(bearGenerator.colors, "color")); console.log("Aggression Stats:"); console.log(dataProcessor.getStatsFor([true, false], "isAggressive")); return bears; }
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
