Do I use Node.js to build a whole website? : <p>The last couple of days I began to teach myself how to create a Website from scratch.</p>

<p>I bought a webspace and fooled around with html, css and javascript and when I wanted to build a online chess game I learned about Node.js</p>

<p>But I don't understand what Node.js is used for because the <a href="https://nodejs.org/dist/latest-v10.x/docs/api/http.html#http_http" rel="nofollow noreferrer">documentation</a> shows how to install and create a fresh server(!) with Node.js and handle requests. </p>

<ul>
<li><p>Do I don't have to use a apache installation on my server anymore? </p></li>
<li><p>Do I create the whole website and all it's pages with Node.js like the index or about page? </p></li>
<li><p>If I use Node.js just for a web application, how can I add the web app to an already existing Apache website's page?</p></li>
</ul>

<p>I think I really got confused and need some help to understand Node.js better since so many are using it.</p>
