5 . What is v8 engine in JavaScript?

V8 JavaScript engine was initially developed for Google Chrome and Chromium web browsers to improve the performance of JavaScript execution. The project’s creator, Lars Bak, created the first version that was released at the same time as the first version of Google Chrome in September 2008. The engine was initially designed solely for execution by web browsers, but the latest versions also execute JS code outside of the browser, enabling server-side scripting.
