What is nodeJS?

NodeJS is an open-source and cross-platform(able to run different type of operating system) runtime environment for executing javascript code outside a browser. It isn't a framework and isn't a programming language. NodeJS often used for building backend services like APIs, Web App and Mobile App. It is an extremely powerful javascript platform used to develop online chat applications, video streaming sites, single-page applications and many other I/O intensive web applications and web apps. It's used in production by large companies such as Paypal, Uber, Netflix and Walmart etc.

Features of NodeJS :

1. It's easy to get started and can be used for prototyping and fast development.
2. It provides fast and highly scalable services.
3. It uses JavaScript everywhere, so it's easy for javscript programmers to build back-end services using nodeJS.
4. Large ecosystem for open source library.

5. It has Asynchronous or Non-blocking in nature. ## Application of NodeJS
