javascript engine









































a javascript engine is a computer program that executes javascript code. the first javascript engines were mere interpreters, but all relevant modern engines utilize just-in-time compilation for improved performance.









































javascript engines are typically developed by web browser vendors, and every major browser has one. in a browser, the javascript engine runs in concert with the rendering engine via the document object model.









































the use of javascript engines is not limited to browsers. for example, the chrome v8 engine is a core component of the popular node.js runtime system.

node.js









































node.js is an open-source, cross-platform javascript run-time environment that executes javascript code outside of a browser. node.js lets developers use javascript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. consequently, node.js represents a "javascript everywhere" paradigm, unifying web application development around a single programming language, rather than different languages for server- and client-side scripts.
