License. MIT [ 3] Website. babeljs .io. 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.
JavaScript ( / ˈdʒɑːvəskrɪpt / ), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior. [ 10] Web browsers have a dedicated JavaScript engine that executes the client code.
Tamarin: An ActionScript and ECMAScript engine used in Adobe Flash. V8: A JavaScript engine used in Google Chrome and other Chromium -based browsers, Node.js, Deno, and V8.NET. GNU Guile features an ECMAScript interpreter as of version 1.9. Nashorn: A JavaScript engine used in Oracle Java Development Kit (JDK) since version 8.
The compiler package comes bundled with a script host that can execute the compiler. It is also available as a Node.js package that uses Node.js as a host. The compiler can "target" a particular edition of ECMAScript (such as ES5 for legacy browser compatibility), but by default compiles for the latest standards.
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.
V8 (JavaScript engine) V8 is a JavaScript and WebAssembly engine developed by Google for its Chrome browser. [ 1][ 4] V8 is free and open-source software that is part of the Chromium project and also used separately in non-browser contexts, notably the Node.js runtime system. [ 1]
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
t. e. A source-to-source translator, source-to-source compiler ( S2S compiler ), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.
