Boa is an open-source implementation of a JavaScript execution engine. The project is developed as a Rust library for embedding the JavaScript engine in Rust applications. Additionally, the authors of Boa provide a command-line interface (CLI) for users to interact with Boa as standalone JavaScript interpreter accessible from a command line. [8]
Web browsers that support JavaScript embed JavaScript engines in order to support JavaScript-enabled web pages. Different browsers use different engines, although there are now multiple browsers based on Chromium which use V8 as their JavaScript engine. V8: A JavaScript engine used in Google Chrome and other Chromium-based browsers (such as ...
The ECMAScript specification is a standardized specification of a scripting language developed by Brendan Eich of Netscape; initially named Mocha, then LiveScript, and finally JavaScript. [7] In December 1995, Sun Microsystems and Netscape announced JavaScript in a press release. [ 8 ]
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
It contained over 5000 tests that touched all aspects of the JavaScript language. [1] [2] The test was created in Russia for testing the conformance of the V8 JavaScript engine used in Google Chrome. [1] As part of phasing out Google Labs, Google has shut down Sputnik. All current Sputnik tests have been incorporated into ECMA's Test262 test suite.
Chakra is a proprietary JScript engine developed by Microsoft. It is used in the Internet Explorer web browser. Microsoft later developed a new JavaScript engine for its Microsoft Edge [Legacy] browser, which is confusingly also called Chakra. Microsoft Edge switched to the V8 JavaScript engine in 2020.
Bun is a JavaScript runtime, package manager, test runner and bundler built from scratch using the Zig programming language. [4] [5] It was designed by Jarred Sumner as a drop-in replacement for Node.js. Bun uses WebKit's JavaScriptCore as the JavaScript engine, [6] unlike Node.js and Deno, which both use V8.
Nashorn is a JavaScript engine developed in the Java programming language originally by Oracle and later by the OpenJDK Community. It relies on the support for dynamically typed languages on the Java Platform (JSR 292) (a concept first realized in the experimental Da Vinci Machine and a standard part of Java 7 and later.)
