OOP

ELI5 — The Vibe Check

OOP is a way of organising code by modelling the world as objects — things that have properties (what they are) and methods (what they do). A Dog object has a name, a breed, and can bark(). Everything is a thing with stuff and actions.

Real Talk

Object-Oriented Programming is a paradigm that structures software around objects — instances of classes — rather than functions and logic alone. Core pillars are encapsulation, inheritance, abstraction, and polymorphism.

Show Me The Code

class Animal {
  constructor(public name: string) {}
  speak(): string { return "..."; }
}

class Dog extends Animal {
  speak(): string { return "Woof!"; }
}

new Dog("Rex").speak(); // "Woof!"
