Top 5 Free Courses to learn Node.js in 2020 - Best of lot

Node JS has completely changed the way JavaScript is used for development. Earlier JavaScript was considered as a client-side language because it runs on a browser and mostly used for client-side validations, animations, and interaction.

All you need to is include node.js script in your application, and you are ready to create server-side applications in JavaScript, which wasn't possible until a few years back.
