bookDeclaring a Class

To declare a class in JavaScript, you use the class keyword followed by the class name and a pair of curly braces to define its body. This structure forms the basis for creating objects with shared properties and behaviors. The class name should be written in PascalCase, meaning each word starts with a capital letter, such as Person or Car. At its simplest, a class can be empty, containing no properties or methods, but it still creates a new type that you can instantiate using the new keyword.
