This course is centered around the conceptual framework that JavaScript, traditionally known for its prototype-based scripting, can be harnessed as an object-oriented programming language. This approach allows for crafting scalable and efficient web applications. The focus will be on understanding the principles of object-oriented programming (OOP) within the context of JavaScript, elucidating how concepts like objects, classes, inheritance, encapsulation, and polymorphism can be implemented in a language that does not have classical OOP constructs. The course aims to demystify the paradigm of object-oriented programming in JavaScript, revealing patterns and best practices that leverage JavaScript’s flexibility to emulate an OOP architecture, ultimately leading to more structured and maintainable code.
