Understanding Object-Oriented Programming Concepts: A Comprehensive Guide for Interviews

Object-Oriented Programming (OOP) is a fundamental aspect of software development that has significantly transformed the way we create and develop applications within this vast field. Having a solid understanding of Object-Oriented Programming (OOP) concepts is not only beneficial but also often the determining factor in succeeding in programming interviews and thriving in the constantly evolving field of technology. This applies to both prospective developers and experienced experts.

Imagine OOP as the architectural blueprint, providing an organized approach for designing, organizing, and managing code. This guide covers the fundamental Object-Oriented Programming (OOP) concepts that are essential to the field of software engineering. If you are getting prepared for a technical interview or trying to strengthen your programming competencies, this exploration will provide you with the required knowledge and insights to confidently navigate the complexities of Object-Oriented Programming (OOP).

Get ready and be prepared to explore the world of Object-Oriented Programming (OOP) with clear understanding and intention. Upon the conclusion of this expedition, you will not only understand these essential concepts, but also utilize their potential to write code that is more brief and effective, so thriving in your upcoming interviews with confidence.

Topics Covered in the series:

  • Classes
  • Objects
  • Encapsulation

I truely belive in the potential of OO-concepts for software development, but is there any relevant environment that uses OOP for web development?

The Javascript class concept has some serious limitations with regard to encapsulation and control of visibility, so I´m not sure we can get the full power of OOP on JS applications.

Absolutely, Object-Oriented Programming (OOP) is widely embraced in web development. While JavaScript has some limitations in terms of encapsulation and visibility control, modern web development frameworks like React and Angular leverage OOP principles to organize code, enhance modularity, and facilitate maintainability. Despite JavaScript's nuances, the application of OOP concepts remains influential and effective in building robust web applications.

I´m not aware of the details of Angular, but as far as I know does React widely relies on the principles of FP. The whole Idea of a virtual DOM makes only sense if you want to build a stateless system ontop of a stateful DOM. In case of React, this makes the management of state transitions far easier, but as we see, it does not solve all the problems the web has today. And the more complex applications get, the more effort will be necessary to deal with the growing complexity. I´m sure, OOP will have a growing impact in the future.

My own experiments to build OOP-applications for the web are pretty promising, but you need to get rid of some bad habits of the HTML/CSS/JS interface first. This works only using global scoped ID´s, which is not the best precondition for OO-code. The DML-library was an approach to solve this issue, but there are too many projects like this that do not get enough momentum to find a larger community. I would really appreciate to find other projects featuring a similar approach.

React uses both: Class components as well as Functional components, it's another thing that the functional components are more popular.
