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.
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.
Just-in-time compilation engines These are new generation ECMAScript engines for web browsers, all implementing just-in-time compilation (JIT) or variations of that idea. The performance benefits for just-in-time compilation make it much more suitable for web applications written in JavaScript .
Cross-compilers to other languages. There are several compilers/transpilers to high-level object languages, with either unrestricted Python, a restricted subset of Python, or a language similar to Python as the source language: Brython, Transcrypt and Pyjs (latest release in 2012) compile Python to JavaScript.
Parse the source code and perform its behavior directly; Translate source code into some efficient intermediate representation or object code and immediately execute that; Explicitly execute stored precompiled bytecode [1] made by a compiler and matched with the interpreter's virtual machine.
In computer science, a compiler-compiler or compiler generator is a programming tool that creates a parser, interpreter, or compiler from some form of formal description of a programming language and machine. The most common type of compiler-compiler is called a parser generator. [1] It handles only syntactic analysis .

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.
