Someone tells me the advantage of OOP?!

Answer 1

It allows you to write clean and readable code.

Answer 2

One of the things I was taught years ago was that OOP allows you to separate the different layers of a system.

Eg
Backend database
Connection Layer
User interface

Now lets just say you want to change the backend database, you should be able to change this, make a few changes at the connection layer, but leave three User Interface alone.

I've never put this into practice, but that's what my lecturer told me 😎

Answer 3

Write less code, do more stuff.
Also code looks a lot cleaner.
