Part 1 / Props / Spread props

If you have an object of properties, you can 'spread' them onto a component instead of specifying each one:

App.svelte
<PackageInfo {...pkg}/>

Conversely, if you need to reference all the props that were passed into a component, including ones that weren't declared with export, you can do so by accessing $$props directly. It's not generally recommended, as it's difficult for Svelte to optimise, but it's useful in rare cases.
