JavaScript Modules. 🧑‍💻 ES6 introduced a powerful way to organize and structure your code using modules. I'll show you how to use imports/exports, the differences between named and default exports, and practical examples.

1️⃣ What are ES6 Modules? Modules are JavaScript files that encapsulate code and allow you to export variables, functions, or classes. This helps keep the code organized and reusable across different application parts.

2️⃣ Exporting Modules You can export items from a module in two main ways: named exports and default exports. • Named Exports: Allows you to export multiple items. • Default Exports: Allows you to export a single item as the default. Let's see examples! 👇

3️⃣ Named Exports Example In this example, we export a constant pi and a function add. You can export as many items as needed!

4️⃣ Importing Named Exports When importing named exports, you must use the same names: You can also rename imports if needed! 🎉

5️⃣ Default Exports Example Here, we export a single function multiply as the default export.. You can only have one default export per module! 🔑

6️⃣ Importing Default Exports When importing a default export, you can name it anything you like ↓ This makes default exports very flexible!

7️⃣ Summary • Use named exports for multiple items. • Use default exports for a single item. • Keep your code modular and organized! 💡 Now, you’re ready to use ES6 modules in your projects!
