Object-oriented Programming in JavaScript

What is Object-oriented Programming (OOP)?

Object-oriented programming (OOP) is a popular programming paradigm or style of programming. It’s been around since ‘70s, but unlike tools and frameworks that come and go, OOP is still very relevant today. That’s because it’s not a programming language or a tool. It’s a style of programming.

Why learn OOP?

OOP helps you manage and reduce complexity in software by building re-usable building blocks (objects). Properly designed objects provide a simple interface and hide the unnecessary complexity from the outside, just like a DVD player! A DVD player has a complex logic board on the inside and a few buttons on the outside. When you press the play button, you don’t care how all those microchips talk to each other.

Object-oriented programming helps you:

• Manage and reduce complexity
• Eliminate redundant code
• Build re-usable building blocks
• Write cleaner code

An essential skills for every developer

OOP comes up in many technical interviews. So if you really want to be a serious developer, you need to understand object-oriented programming. As a technical interviewer myself, if I see a candidate with OOP on their resume, that candidate stands out to me.�

It may interest you to know that many of the popular frameworks out there that you might be using are actually designed with OOP concepts in mind. Angular is an example of such frameworks!�
