Now with that, that's it for this module.
We optimized images.
We ensured that we don't load
those super huge images therefore
and we also optimized our metadata, our page metadata.
With the head component offered by Next.js
which we can include in our pages
to set the title meta `description
or any other head section tags
from inside our page components.
We also learned about Underscore app
and Underscore Document JS which are files that allow us
to set up certain settings and elements
which are being used across all pages in our application.
With that we can set up general metadata
or for example, inject extra HTML content
into the load at HTML document.
And with that, we got a couple of important tools
which we will need to build
a real applications with Next.js.
Because of course on real applications
you wanna have metadata in the head section
and you wanna have optimized images.
And now, you know how to do both in your next apps.
