JavaScript classes provide a way to create objects with properties and methods. They are like blueprints that define how an object should be created. Classes allow you to reuse code and create new objects that share the same properties and methods. You can create a class using the class keyword and define properties and methods inside its body. You can create new instances of the class using the new keyword. Classes are a powerful feature of modern JavaScript (ES6 and newer) and are used extensively in web development (both frontend and backend).
OOP (which stands for Object-Oriented Programming) is a programming paradigm that focuses on creating objects that contain data and behavior, allowing for code reuse, encapsulation, and abstraction.
This series of tutorials will guide you through everything, from basic to advanced, about classes and OOP in JavaScript.
