•You want to scrape data from websites that use a lot of JavaScript
•You need to generate PDFs or screenshots of web pages programmatically

Quick start

1Launch a browser instance with `const browser = await puppeteer.launch();`
2Create a new page with `const page = await browser.newPage();`
3Navigate to a webpage with `await page.goto('https://example.com');`
4Take a screenshot with `await page.screenshot({ path: 'example.png' });`
5Close the browser instance with `await browser.close();`

Ready-to-paste prompt
