JavaScript’s module system is a powerful tool for organizing and sharing your code. In this article, we’ll dive into the world of module exports, exploring how to effectively share functionality across your projects.

Whether you’re a seasoned developer or just starting your JavaScript journey, this guide will equip you with the knowledge to master module exports and take your coding skills to new heights.

Understanding Module Exports

In JavaScript, modules are self-contained units of code that encapsulate related functionality. When you create a module, you can choose to expose certain parts of it to the outside world through the export keyword. This allows other modules to access and use the exported functionality, promoting code reuse and maintainability. Here's a simple example of a module that exports a function:

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

In this case, the add function is made available for other modules to use.
