Understanding Modules and Import and Export Statements in JavaScript
As the importance of JavaScript in web development grows, there is a bigger need to use third-party code for common tasks, to break up code into modular files, and to avoid polluting the global namespace.

In this tutorial, you will learn what a JavaScript module is and how to use import and export to organize your code.
