JavaScript engines is a complex topic, and knowing about these engines you will code even better, and to code optimized for web.
["Virtual Machines"]
A JavaScript engine has a type of "virtual machine" and this high-level language was designed for web-development. There are many "virtual machines" I explain later on this topic.
[What is JavaScript engine]
The basic job of JavaScript engine is to take a piece of code, and convert it so fast, optimizing code and it can be interpreted by the browser.
In each JavaScript engine has your own particular version followed by ECMAScript. There are many different engines world-wide, each one is designed to work.
i.e.: Node.js is one of the awesome and known engines. Node otherwise, is good for runtime environment. And so on...
Those engines and a huge variety are available to analyze, parse, and execute client-side code or server-side (Node.js) in every browser version.
I hope you all enjoyed,
