Node.js and JavaScript

In the beginning, JavaScript could only be used inside of web browsers, but Node.js gives you the ability to use JavaScript on the server. You can write your code for the server entirely in JavaScript instead of having to use another “server-side” programming language like Python or PHP.

What can you do with Node.js?

Node.js set JavaScript free from the web browser. With Node.js, you can use JavaScript everywhere. There are Node.js libraries that let you use JavaScript for desktop applications, artificial intelligence, machine learning, mobile app development, static site generators, databases, and creating dynamic web applications.

Can Node.js code run in the browser?

It cannot, actually. Even though both web browsers and Node.js run JavaScript code, they are different implementations with different features and functionality added on top of the core JavaScript language. However, several tools can take code written for Node.js and convert it to JavaScript code that will run in the browser.
