// math.js (CommonJS)
function add(a, b) {
  return a + b;
}

function subtract(a, b) {
  return a - b;
}

module.exports = {
  add,
  subtract
};

// app.js (CommonJS)
const math = require('./math');
console.log(math.add(5, 3)); // 8

// math.mjs (ES Module)
export function add(a, b) {
  return a + b;
}

export function subtract(a, b) {
  return a - b;
}

// app.mjs (ES Module)
import { add, subtract } from './math.mjs';
console.log(add(5, 3)); // 8

नाम दिया गया एक्सपोर्ट्स

// Multiple named exports
export function sayHello() {
  console.log('Hello');
}

export function sayGoodbye() {
  console.log('Goodbye');
}

// Alternative: export list at the end
function add(a, b) {
  return a + b;
}

function subtract(a, b) {
  return a - b;
}

export { add, subtract };

डिफ़ॉल्ट निर्यात

// Only one default export per module
export default function() {
  console.log('I am the default export');
}

// Or with a named function/class/object
function mainFunction() {
  return 'Main functionality';
}

export default mainFunction;

नामित निर्यात आयात करना

// Import specific named exports
import { sayHello, sayGoodbye } from './greetings.mjs';
sayHello(); // Hello

// Rename imports to avoid naming conflicts
import { add as sum, subtract as minus } from './math.mjs';
console.log(sum(5, 3)); // 8

// Import all named exports as an object
import * as math from './math.mjs';
console.log(math.add(7, 4)); // 11

डिफ़ॉल्ट और नामित निर्यात आयात करना

// Import both default and named exports
import main, { VERSION } from './main.mjs';
console.log(VERSION); // 1.0.0
main(); // Main function
