NodeJs

The Superpower of JavaScript.

Imagine you’re at the circus, and you see a magician pulling rabbits out of a hat. But instead of rabbits, this magician is pulling incredible things like real-time chat apps, API servers, and microservices. The secret behind this magic? Node.js.

Node.js is a runtime environment that lets you run JavaScript outside of a browser, on your server. Traditionally, JavaScript was the language of the browser, but Node.js brought it to the backend, allowing developers to use JavaScript for both the front and back ends of their applications. It's like having a superhero who can do both front-end tricks and back-end stunts. Talk about multitasking!
