⟹Nodejs

➡Node.js is an open source server framework.

➡Node.js allows you to run JavaScript on the server.

➡Node.js runs on various platforms (Windows, Linux, Unix, Mac OS X, etc.)

⟹Here is how Node.js handles a file request

 ➡Sends the task to the computer's file system.

 ➡Ready to handle the next request.

 ➡When the file system has opened and read the file, the server returns the   content  to the client.

 

 

Node.js eliminates the waiting, and simply continues with the next request.
Node.js runs single-threaded, non-blocking, asynchronously programming, which is very memory efficient.
