A JavaScript engine is a software component that executes JavaScript code. The first JavaScript engines were mere interpreters, but all relevant modern engines use just-in-time compilation for improved performance. [1] JavaScript engines are typically developed by web browser vendors, and every major browser has one
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.
Jint: Javascript interpreter with integrated engine for .NET; Narcissus: JavaScript implemented in JavaScript (a meta-circular evaluator), intended to run in another JavaScript engine, of theoretical and educational nature only. JS-Interpreter A lightweight JavaScript interpreter implemented in JavaScript with step-by-step execution.
The framework is designed to create desktop applications using web technologies (mainly HTML, CSS and JavaScript, although other technologies such as front-end frameworks and WebAssembly are possible) that are rendered using a version of the Chromium browser engine and a back end using the Node.js runtime environment.

The engine powers the Firefox web browser and has used multiple generations of JavaScript just-in-time (JIT) compilers, including TraceMonkey, JägerMonkey, IonMonkey, and the current WarpMonkey. It is the first JavaScript engine , written by Brendan Eich at Netscape Communications, and later released as open source and currently maintained by ...
Babel is a free and open-source JavaScript transcompiler that is mainly used to convert ECMAScript 2015+ (ES6+) code into backwards-compatible JavaScript code that can be run by older JavaScript engines. It allows web developers to take advantage of the newest features of the language. [4]
In 2023, the Maglev SSA-based compiler was added, which is 10 times slower than Sparkplug but 10 times faster than TurboFan, bridging the gap between Sparkplug and TurboFan for less frequently run loops that do not get "hot" enough to be optimised by TurboFan, as is the case for most web applications that spend more time interacting with the ...
JavaScript asynchronous, event-based I/O. Influenced by systems like Ruby's Event Machine, Perl's POE or Python's Twisted. Plenty of modules available. Opera: Futhark: Opera Unite JavaScript is the server-side language used to develop services for the Opera Unite feature of the Opera browser. This is a server built into the browser.
