🔁 Recursion in Python

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)
        

💾 JavaScript Async/Await

async function getData() {
    const res = await fetch('https://api.example.com/data');
    const data = await res.json();
    console.log(data);
}
        

🧠 Object-Oriented Programming (OOP)

class Dog:
    def __init__(self, name):
        self.name = name

    def bark(self):
        print(self.name + " says woof!")

dog = Dog("Rex")
dog.bark()
