What paradigm is Javascript

// JavaScript is a Multi-Paradigm Language:
// 1. Prototype-based Object-Oriented Programming (OOP)
class User { constructor(name) { this.name = name; } }

// 2. Functional Programming (First-class functions, pure functions, immutability)
const double = x => x * 2;
[1, 2, 3].map(double);

// 3. Event-Driven Asynchronous Programming
setTimeout(() => console.log('Event driven'), 100);
