Introduction
This module explores two fundamental programming paradigms: Object-Oriented Programming (OOP) and Functional Programming (FP), to get a deeper understanding of coding in JavaScript. JavaScript, being a multi-paradigm language, gives us the unique flexibility to utilize both OOP and FP principles, often blending them together to create more robust and versatile code.
Our primary focus will be on Object-Oriented Programming. We will explore JavaScript’s objects and classes which enable us to model real-world entities and manage complex applications with ease. You’ll learn how to create reusable code, maintain state, and structure your programs using concepts such as encapsulation, inheritance, and polymorphism.
However, to fully appreciate the power of JavaScript, it’s useful to understand how it accommodates Functional Programming as well. Functional programming emphasizes immutability, first-class functions, and declarative code, offering a different approach to managing complex applications. We’ll touch upon the core principles of FP, illustrating how they complement OOP. The majority of the content on Functional Programming is provided as additional content, as you are more likely to encounter OOP-based systems in practice.
