/// Points to be noted :

///  Node js is an open source, Java Script runtime 
///  which is asynchronous and singlethreaded platform
///  now , in a PHP : 
///  1) It will take the request
///  2) It will send the request to the computer
///  3) It will wait for the computer to read the file
///  4) recieves the response 
///  5) sends back to the UI
///  6) Gets ready to take another requesst


///  But Node JS doesn't wait for the computer to respond. 
///  While the computer is reading the file, it will be ready for the next request
///  That is the advantage of Node JS.
