How do print the console output of the page in puppeter as it would appear in the browser?

  page.on('console', async e => {
    const args = await Promise.all(e.args().map(a => a.jsonValue()));
    console.log(...args);
  });

or

  page.on('console', async e => {
    const args = await Promise.all(e.args().map(a => a.jsonValue()));
    console[e.type() === 'warning' ? 'warn' : e.type()](...args);
  });

works
