Hello there! Today, we're diving into JavaScript classes, focusing on attributes and methods. Attributes are characteristics, whereas methods define behaviors. You'll learn these concepts through a Dog class. By the end of the lesson, you should be able to use attributes and methods in JavaScript classes effectively.

Think of attributes as properties. For a Dog class, the attributes might include name: "Fido", breed: "Poodle", color: "White". These attributes describe the characteristics of a dog like Fido.

We add attributes to the class constructor. Below, we're setting the name, breed, and color for the Dog class:

class Dog {
    name = 'Fido';
    breed = 'Poodle';
    color = 'White';
}

When we create an instance:

const fido = new Dog();
console.log(fido.name); // Prints: Fido
console.log(fido.breed); // Prints: Poodle
console.log(fido.color); // Prints: White

We see Fido, an object of the Dog class.

Methods are actions that instances of a class can perform. For the Dog class, behaviors might include bark(), eat(), and sleep(). Methods are functions defined within the class.
