A multi-paradigm programming language is a language that supports more than one programming paradigm. This flexibility allows developers to choose the best approach for solving a problem, whether it be procedural, object-oriented, functional, or another paradigm.

Key Paradigms Supported by Multi-Paradigm Languages:

1. Procedural Programming: Focuses on procedures or routines.
2. Object-Oriented Programming (OOP): Organizes code into objects with properties and methods.
3. Functional Programming (FP): Emphasizes pure functions, immutability, and first-class functions.
4. Structured Programming: Uses control structures like loops and conditionals for clear, maintainable code.
5. Event-Driven Programming: Responds to events or user actions.

Example: JavaScript as a Multi-Paradigm Language
JavaScript is a prime example of a multi-paradigm language. It supports:

• Procedural Programming: Writing code as a sequence of steps.
• Object-Oriented Programming: Using prototypes or ES6 classes.
• Functional Programming: Leveraging first-class functions and higher-order functions.
• Structured Programming: Using control structures like if, for, and while.
• Event-Driven Programming: Handling user interactions or asynchronous events.

Code Examples:

1. Procedural Programming:

function add(a, b) {
    return a + b;
}
const result = add(2, 3); // 5

2. Object-Oriented Programming:

class Person {
    constructor(name) {
        this.name = name;
    }
    greet() {
        return `Hello, ${this.name}!`;
    }
}
const person = new Person('Alice');
console.log(person.greet()); // "Hello, Alice!"

3. Functional Programming:

const numbers = [1, 2, 3, 4];
const doubled = numbers.map(num => num * 2); // [2, 4, 6, 8]

4. Structured Programming:

function checkNumber(num) {
    if (num > 0) {
        return "Positive";
    } else if (num < 0) {
        return "Negative";
    } else {
        return "Zero";
    }
}

5. Event-Driven Programming:

document.getElementById('myButton').addEventListener('click', () => {
    console.log('Button clicked!');
});

Key Benefits of Multi-Paradigm Languages:

1. Flexibility: Developers can choose the best paradigm for the task.
2. Expressiveness: Combines the strengths of multiple paradigms.
3. Adaptability: Suitable for a wide range of applications, from web development to data processing.
