CommonJS

CommonJS is a standard for organizing and sharing code modules in JavaScript, primarily used for server-side programming. It allows developers to break down complex programs into smaller, reusable pieces (modules) that can be imported and used in different parts of an application. This system enables better code management, reusability, and maintainability, particularly in environments like Node.js. Think of it as a standardized way for JavaScript files to communicate and share functionalities, similar to how a library system grants access to books across various locations.
