IMDb doesn't use iframe anymore

[honzajavorek]

The examples in Scraping iFrames do not work and IMDb doesn't use iframe anymore:

The code in the first block is missing an import. Moreover, after adding the import and running the code, I obtain the following warning and error:

 Puppeteer old Headless deprecation warning:
  In the near future `headless: true` will default to the new Headless mode
  for Chrome instead of the old Headless implementation. For more
  information, please see https://developer.chrome.com/articles/new-headless/.
  Consider opting in early by passing `headless: "new"` to `puppeteer.launch()`
  If you encounter any bugs, please report them to https://github.com/puppeteer/puppeteer/issues/new/choose.

^[[Bfile:///Users/marco/Onboarding/puppeteer-playwright/iframe.js:8
await page.waitFor(5000); // we need to wait for Twitter widget to load
      	^

TypeError: page.waitFor is not a function
	at file:///Users/marco/Onboarding/puppeteer-playwright/iframe.js:8:12
	at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

If I substitute the waitFor function with the deprecated waitForTimeout one, the code works. Anyway, the IMDb website seems not to use any frame anymore, so this example is obsolete.
