Node.js relies on nghttp2 for HTTP support. As of version 20, Node.js uses the ada library which provides up-to-date WHATWG URL compliance. As of version 19.5, Node.js uses the simdutf library for fast Unicode validation and transcoding. As of version 21.3, Node.js uses the simdjson library for fast JSON parsing.
Google created V8 for its Chrome browser, and both were first released in 2008. [4] The lead developer of V8 was Lars Bak, and it was named after the powerful car engine. [5] For several years, Chrome was faster than other browsers at executing JavaScript. [6] [7] [8] The V8 assembler is based on the Strongtalk assembler. [9]
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 ...
While justified by the Yarn team as a need to address multiple design flaws in the typical Node.js module resolution, this change required some support from other projects in the ecosystem which took some time to materialise, adding friction to the migration from Yarn 1.22. to Yarn 2.0.

In such an optimising compiler, no conversions are performed when asm.js code calls other asm.js code, as the required type specifiers mean it is guaranteed that values will already have the correct type. Furthermore, rather than performing a floating-point addition and converting to an integer, it can simply do a native integer operation.
A distinctive feature of the engine is that it JIT compiles scripts on a separate CPU core, parallel to the web browser. [1] [2] Though Microsoft has in the past pointed out that other elements, such as rendering and marshalling, are just as important for a browser's overall performance, [3] their improvements to the engine were in response to evolving competing browsers, compared to which IE8 ...
