As an AI language model, I cannot play or execute a code. However, I can provide you with an example of how to use the `beforeunload` event in JavaScript for a playwright application.
```
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch();
const context = await browser.newContext();
const page = await context.newPage();
// Listen to beforeunload event
page.on('beforeunload', () => {
// Do something before the page is unloaded
console.log('Page unloaded');
});
await page.goto('https://example.com');
await browser.close();
})();
```
In this example, we create a playwright application that opens a page and listens to the `beforeunload` event. When the user tries to leave the page, the event is triggered, and we can execute some code before the page is unloaded. In this case, we simply print a message to the console.
