In this video, we’ll be covering JavaScript Modules and the essential concepts of import and export! Modules are a powerful feature in JavaScript that allow you to organize your code better, make it reusable, and keep your projects more manageable. This tutorial will help you understand how modules work and how to use import and export statements to share code across different files. Let’s dive in and start building modular JavaScript code! 🚀
