const pt = require('puppeteer');
pt.launch().then(async browser => {
   //browser new page
   const p = await browser.newPage();
   //set viewpoint of browser page
   await p.setViewport({ width: 1000, height: 500 })
   //launch URL
   await p.goto('https://www.tutorialspoint.com/questions/index.php')
   //obtain page title
   console.log("Page title: " + await p.title())
   //obtain URL
   console.log("Url: " + await p.url())
   //browser close
   await browser.close()
})
