Understanding CommonJS vs. ES Modules in JavaScript

JavaScript has two major module systems: CommonJS and ES Modules. CommonJS is used for server-side development in Node.js and provides a reliable and powerful tool for managing dependencies. ES Modules, on the other hand, is a modern module system built into the JavaScript language, suitable for both client-side and server-side development. The primary differences between these module systems are the loading system, caching mechanism, and export mechanisms. When choosing between CommonJS and ES Modules, developers should consider factors such as their target platform and the level of front-end or back-end complexity.
