OOP is a programming paradigm based on the concept of "objects", which can contain data and code.

Class: A blueprint or template for creating objects. (e.g., The blueprint for a Car).
Object: An instance of a class. (e.g., Your specific red Toyota is an object of the Car class).
Encapsulation: Hiding the internal details of how an object works and only showing what is necessary. (e.g., You press the gas pedal, you don't need to know how the fuel injection works).
Inheritance: Creating a new class based on an existing one. (e.g., An "Electric Car" inherits features from a "Car").
Polymorphism: The ability of different objects to respond to the same command in their own way. (e.g., Both a "Car" and a "Bicycle" have a move() method, but they move differently).
Abstraction: Focusing on what an object does instead of how it does it. (e.g., Using a TV remote without knowing the electronics inside).

Logic First

OOP helps us model the real world in code. It makes large programs easier to maintain, reuse, and scale.
