Classes

Classes in JavaScript are a template for creating objects. As we learned, unlike many other languages, it's easy to create JavaScript objects without classes, but that doesn't mean classes aren't useful.

class User {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }
}

const user = new User("Lane", 100);

The class declaration creates a new class
The constructor method is a special method that's called when a new instance of the class (object) is created
The new keyword calls the constructor method and creates a new instance of the class

Assignment

Textio messages include three properties:

recipient: The person receiving the message.
sender: The person sending the message.
body: The content of the message.
