Part 1 / Introduction / Nested components
It would be impractical to put your entire app in a single component. Instead, we can import components from other files and include them in our markup.
Add a <script> tag to the top of App.svelte that imports Nested.svelte...
App.svelte
<script>
	import Nested from './Nested.svelte';
</script>...and include a <Nested /> component:
App.svelte
<p>This is a paragraph.</p>
<Nested />Notice that even though Nested.svelte has a <p> element, the styles from App.svelte don't leak in.
Component names are always capitalised, to distinguish them from HTML elements.
