 - when extracting logic, it's better to take advantage of runes' universal reactivity: You can use runes outside the top level of components and even place them into JavaScript or TypeScript files (using a `.svelte.js` or `.svelte.ts` file ending)
 - when creating shared state, you can create a `$state` object containing the values you need and then manipulate said state
 
+```ts
+/// file: state.svelte.js
+export const userState = $state({
+	name: 'name',
+	/* ... */
+});
+```
+
+```svelte
+<!--- file: App.svelte --->
+<script>
+	import { userState } from './state.svelte';
+</script>
+
+<p>User name: {userState.name}</p>
+<button onclick={() => {
+	userState.name = 'new name';
+}}>
+	change name
+</button>
+```

 Stores are still a good solution when you have complex asynchronous data streams or it's important to have more manual control over updating values or listening to changes. If you're familiar with RxJs and want to reuse that knowledge, the `$` also comes in handy for you.

 E2E (short for 'end to end') tests allow you to test your full application through the eyes of the user. This section uses [Playwright](https://playwright.dev/) as an example, but you can also use other solutions like [Cypress](https://www.cypress.io/) or [NightwatchJS](https://nightwatchjs.org/).
 
-To get start with Playwright, either let you guide by [their VS Code extension](https://playwright.dev/docs/getting-started-vscode), or install it from the command line using `npm init playwright`. It is also part of the setup CLI when you run `npx sv create`.

 After you've done that, you should have a `tests` folder and a Playwright config. You may need to adjust that config to tell Playwright what to do before running the tests - mainly starting your application at a certain port:

 > It was always possible to use component callback props, but because you had to listen to DOM events using `on:`, it made sense to use `createEventDispatcher` for component events due to syntactical consistency. Now that we have event attributes (`onclick`), it's the other way around: Callback props are now the more sensible thing to do.
