📘 JavaScript Classes — Introduction

✅ What is a Class?

A class is a blueprint for creating objects. It bundles data (properties) and actions (methods) into one convenient structure.

📌 Basic Class Syntax

jsCopyEditclass Person {
  constructor(name, age) {
    this.name = name; // Property
    this.age = age;   // Property
  }

  greet() {  // Method
    console.log(`Hello! My name is ${this.name} and I am ${this.age} years old.`);
  }
}

const person1 = new Person("Alice", 25); // Create new object
person1.greet(); // Hello! My name is Alice and I am 25 years old.

📌 Key Points

• class keyword declares a class.
• constructor() is a special method to initialize new objects.
• Methods inside the class define behaviors.
• Use new keyword to create instances (objects) of the class.

📌 Why Use Classes?

• Cleaner syntax for creating objects.
• Makes object-oriented programming (OOP) easier.
• Supports inheritance and reuse of code.
• Helps organize code in bigger projects.

🧪 Try it Yourself!

jsCopyEditclass Animal {
  constructor(type) {
    this.type = type;
  }

  speak() {
    console.log(`This is a ${this.type}`);
  }
}

const dog = new Animal("dog");
dog.speak(); // This is a dog
