Is node js is middleware? : <p>When I have started learning nodeJs , I was consider this as a server side back end language . But then I came to know from a senior developer that NodeJs is not back end , it is middle ware . </p>

<p>I don't find any specific article for this point .. can anyone clear this . Is it only middle ware , or can be use as middle ware language with a server side language ?</p>
