Based on my observation, the book that I am reading about JavaScript states that there's an OOP with JavaScript? It doesn't tell much about it, I mean it wasn't explained how to define a class. Can someone give me a sample snippet?
Thanks

In JavaScript, classes are the special type of functions. We can define the class just like function declarations and function expressions. The JavaScript class contains various class members within a body including methods or constructor. The class is executed in strict mode.
In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming.
JavaScript is not a class-based object-oriented language. But it still has ways of using object oriented programming (OOP).
One way to define a class is using a class declaration. To declare a class, you use the class keyword with the name of the class ("Rectangle" here).
JavaScript is Prototype based and not class based.
Prototype-based programming is a style of object-oriented programming in which classes are not present, and behavior reuse (known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes. This model can also be known as class-less, prototype-oriented or instance-based programming. Delegation is the language feature that supports prototype-based programming.
