Describe the bug

Thanks for the awesome project! Very excited about this. Stumbling into this issue after npm install playwright and trying a simple test script from the readme examples.

@arturi I suppose this is because this https://github.com/microsoft/playwright/pull/840 Cause it isn’t released yet, you should use context:

const playwright = require('playwright');

(async () => {
  for (const browserType of ['chromium', 'firefox', 'webkit']) {
    const browser = await playwright[browserType].launch();
    const context = await browser.newContext();
    const page = await context.newPage('http://example.com');
    await page.screenshot({ path: `example-${browserType}.png` });
    await browser.close();
  }
})();

We will be bringing back browser.newPage in 0.11, but for now please use newContext as suggested in the docs and above.
