Usage

You can use the functions by requiring the module in your Node.js application. Here’s how you can do it:

const { add, subtract, multiply, divide } = require('./index');

console.log(add(2, 3));         // Output: 5
console.log(subtract(5, 2));    // Output: 3
console.log(multiply(2, 3));    // Output: 6
console.log(divide(6, 2));      // Output: 3

// Handle division by zero
try {
  console.log(divide(6, 0));
} catch (error) {
  console.error(error.message); // Output: Cannot divide by zero
}
