Node.js is an open-source server environment, built on Chrome's JavaScript V8 Engine, that executes JavaScript code outside of a browser. node.js lets us build fast and scalable network applications using Javascript language, which has the shortest learning curve among all other languages because it uses similar syntax as used in HTML & CSS.

node.js is very lightweight and efficient interpreter that runs single thread event loop first and then move to other threads for parallel execution of tasks based on I/O events e.g. file reads or writes etc., nodeJs make use of asynchronous calls thus results in much faster execution times i.e node js lacks blocking mechanism like Operating System (OS) processes or Threads due to which nodeJS can handle multiple request in single process space and node.js is much memory efficient than other scripting languages because nodeJS handles one request at a time unlike other multi-threading models where several requests can be executed in parallel and nodeJS creates less garbage objects thus requires less CPU cycles and memory allocation for execution of program/code, nodeJs use non-blocking I/O calls to handle concurrent connections and hence node.js applications need very little memory or no dedicated threads or processes to manage concurrency, resulting in lighter system resource usage.
