Node.JS is an open-source, cross platform JavaScript run-time environment for executing JavaScript code server-side. It is built on Google Chrome’s JavaScript Engine and is used for creating scalable, event-driven applications.

Node.JS is not written in JavaScript, but it uses the JavaScript as an interpretive language for server-side request/response processing. It is intended to run on a dedicated HTTP server and to utilize a single thread with one process at a time.

Code built on Node platform does not follow the traditional model of receive, process, send, wait, receive. Rather, it processes incoming requests in a constant event stack and sends trivial requests one after the other without waiting for responses.


  1. One of the most significant benefits is that it does not block input/output.
  2. It is an open-source technology which includes a shared repository of dynamic tools and modules.
  3. It trims all the problems involved with forming separate threads and instead uses a single thread.
  4. JavaScript is now present in the browser as well as server, all thanks to Node.JS
  5. It runs in a similar manner and is flexible in usage
  6. It helps to build real-time web applications at a swift pace.
  7. The event-driven architecture caters to both the client-side as well as server-side that are written in JavaScript.
  8. It comes to rescue to proxy different services that have different response times or for gathering data from various sources.
  9. With time, more and more developers are jumping on Node.JS due to which hosting is also gaining momentum.
  10. It consists of a growing open source community that has delivered numerous spectacular modules.
