What is jacaScript engine?

A program or interpreter that understands and executes JavaScript code.

JavaScript engines are commonly found in web browsers, including JavaScriptCore (Nitro) in Safari, V8 in Chrome and opera, SpiderMonkey in Firefox, and Chakra in Microsoft Edge.

The basic job of a JavaScript engine, when all is said and done, is to take the JavaScript code that a developer writes and convert it to fast, optimized code that can be interpreted by a browser or even embedded into an application.
