Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting.
The most popular runtime system for non-browser usage is Node.js. JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard. [11] It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative ...

MEAN (MongoDB, Express.js, AngularJS (or Angular), and Node.js) [1] is a source-available JavaScript software stack for building dynamic web sites and web applications. [2] A variation known as MERN replaces Angular with React.js front-end, [3] [4] and another named MEVN use Vue.js as front-end.
V8 from Google is the most used JavaScript engine. Google Chrome and the many other Chromium-based browsers use it, as do applications built with CEF, Electron, or any other framework that embeds Chromium. Other uses include the Node.js and Deno runtime systems. SpiderMonkey is developed by Mozilla for use in Firefox and its forks.
For example, Dojo abstracts the differences among diverse browsers to provide APIs that will work on all of them (it can even run on the server under Node.js); it establishes a framework for defining modules of code and managing their interdependencies; it provides build tools for optimizing JavaScript and CSS, generating documentation, and ...
JavaScript Python MDN Web Docs , previously Mozilla Developer Network and formerly Mozilla Developer Center , is a documentation repository and learning resource for web developers .
CommonJS is a project to standardize the module ecosystem for JavaScript outside of web browsers (e.g. on web servers or native desktop applications). CommonJS's specification of how modules should work is widely used today for server-side JavaScript with Node.js. [ 1 ] It is also used for browser-side JavaScript, but that code must be packaged ...
