This makes it easier to reason about the application’s behavior and reduces the likelihood of bugs.
Node.js: The Backend Runtime Environment
Node.js is a runtime environment that facilitates the execution of JavaScript code outside the confines of a web browser. It leverages the V8 JavaScript engine, which serves as the backbone of Google Chrome, to execute JavaScript code on the server side. JavaScript can construct web servers, command line tools, and desktop applications.
A pivotal characteristic of Node.js is its non-blocking, event-driven architecture. This enables Node.js to handle numerous connections concurrently without succumbing to the hindrances of blocking operations. Consequently, Node.js is exceptionally well-suited for developing real-time web applications like chat platforms or online games.
Furthermore, Node.js boasts an extensive ecosystem of modules and packages that can be utilized to enhance its functionality. These modules are effectively managed through npm, the Node.js package manager, simplifying the process of incorporating new features into your application.
