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 .
The uses of the listed engines vary widely; some of these are engines intended for browsers that can run ECMAScript code on websites that include ECMAScript, like V8 (used in both Google Chrome and Node.js) and SpiderMonkey; some are intended for specific platforms (like Tamarin, Espruino, Rhino, Nashorn, and GraalJS).
In May 2021, StackBlitz released WebContainers, a containerization solution that allowed server-side runtime environments such as Node.js to operate fully with web browsers. The company stated that the technology could boot development environments in less than a second, and was more secure than local environments due to running fully within ...
[10] Web browsers have a dedicated JavaScript engine that executes the client code. These engines are also utilized in some servers and a variety of apps. 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 also uses various APIs to enable functionality such as native integration with Node.js services and an inter-process communication module. Electron was originally built for Atom [ 5 ] and is the main GUI framework behind several other open-source projects including GitHub Desktop , Light Table , [ 8 ] Visual Studio Code , WordPress Desktop ...
Bun uses WebKit's JavaScriptCore as the JavaScript engine, [6] unlike Node.js and Deno, which both use V8. It supports bundling, minifying , server-side rendering ( Svelte , Nuxt.js , Vite ). Bundling refers to the process of combining multiple files and assets like JavaScript , CSS , and HTML into a single file, or a smaller number of files ...
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 ...
Other uses include the Node.js and Deno runtime systems. SpiderMonkey is developed by Mozilla for use in Firefox and its forks. The GNOME Shell uses it for extension support. JavaScriptCore is Apple's engine for its Safari browser. Other WebKit-based browsers and the Bun runtime system also use it. KJS from KDE was the starting point for its ...
