CommonJSES

CommonJSES refers to a set of JavaScript APIs designed for general-purpose programming, as opposed to browser-specific scripting. It emerged from the CommonJS specification, which aimed to provide a standardized module system for JavaScript outside of web browsers. The "ES" in CommonJSES signifies its intention to be compatible with or inspired by the ECMAScript standard. This initiative sought to bring features like module loading, package management, and standard library functions to server-side JavaScript environments.

Key aspects of CommonJSES include the `require` and `module.exports` syntax for defining and importing modules, which has become a de facto standard in Node.js. This modular approach allows developers to break down large applications into smaller, manageable files, improving organization and reusability. While not a formal, universally adopted standard in the same way as ECMAScript modules (ESM), the principles and patterns established by CommonJS have profoundly influenced the JavaScript ecosystem, particularly in server-side development. Many tools and frameworks still leverage or support CommonJS modules, making its understanding relevant for JavaScript developers.
