title: is there a difference between using built in Head component from nextjs and head tag from as jsx
body: <p>I hope that this question is suitable for this comunity.
  I am confused on how build in Head component in nextjs work.
  My guess is that as a default nextjs creates metadata and Head replaces or add to it. However I am not sure what would happen if I create my own metadata not with buildIn Head but with a custom meta component like this:</p>
  <pre><code>&lt;html len= {leng || &quot;en&quot;}&gt;
  &lt;head&gt;
  ///some data 
  &lt;/head&gt;
  </code></pre>
  <p>I guess it doesn't really matter but I want to learn the the need for a buildIn Head component.
  also I want to be able to change language of the page and It seems easier with my custom component?</p>
