In this article, we are going to learn about The Javascript engine V8. Node js is built up on the V8 engine, which helps us to run JavaScript on our computer.

Let's Begin.

We all know at earlier times Javascript was meant to be run on the browser and its mostly used for the front-end . But now we are using Javascript in front-end, back-end, and whatnot. These all things are possible because of the V8 engine.

What is a Javascript Engine

JavaScript Engine is a component that converts that Javascript code to machine code. In earlier times JavaScript engine was only used in browsers. There are many JavaScript Engines out there Some of the browsers and their Javascript Engines are listed below.

• Google Chrome - V8
• Mozilla Firefox - Spider Monkey
• Safari - Javascript Core Webkit

V8 Engine

V8 is Google’s open-source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others.it's the thing that takes our JavaScript and executes it while browsing with Chrome. V8 provides an edge as it allows JavaScript to run much faster, which improves users’ experience of the web, paves the way for the development of web applications, and spurs rapid growth of server-side JavaScript through projects like Node.js.

Node js build upon the Javascript Engine V8 and It's one of the main reasons that we can use javascript in back-end development. so V8 became the engine that now powers an incredible amount of server-side code written in JavaScript.

Conclusion

In this article, we learned about Javascript engines mainly V8 engines. V8 is a JavaScript engine developed by the Chromium Project for Google Chrome and Chromium web browsers. We are having fun using Javascript in server-side is because of the node environment which builds upon V8. I hope you learned something new here.
