Understanding module.exports and exports in Node.js
In programming, modules are self-contained units of functionality that can be shared and reused across projects. They make our lives as developers easier, as we can use them to augment our applications with functionality that we haven't had to write ourselves. They also allow us to organize and decouple our code, leading to applications that are easier to understand, debug and maintain. In this article, I'll examine how to work with modules in Node.js, focusing on how to export and consume them. Different Module Formats As JavaScript originally had no concept of modules, a variety of competing formats have emerged over time. Here's a list of the main ones to be aware of: The Asynchronous Module Definition (AMD) format is used in browsers and uses a define function to define modules. The CommonJS (CJS) format is used in Node.js and uses require and module.exports to define dependencies and modules. The npm ecosystem is built upon this format. The ES Module (ESM) ...
