Hello there! Today, we're delving into TypeScript classes, focusing on attributes and methods. Attributes define properties, whereas methods define actions. Through the Dog class, you'll learn these concepts. By the end of the lesson, you should be capable of effectively using attributes and methods in TypeScript classes.

Attributes can be regarded as properties. For a Dog class, the attributes can include name: "Fido", breed: "Poodle", color: "White". These attributes depict a dog's characteristics, such as those of Fido.

In the Dog class, we define attributes like name, breed, and color directly. These attributes represent a dog's characteristics and are set with default values:

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

To instantiate the class and access these attributes, you would do the following:

let fido = new Dog();

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

Here, Fido is an object of the Dog class.

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