Puppeteer can also be used to control the Chrome browser, but it works best with the version of Chromium it is bundled with. There is no guarantee it will work with any other version. Use <code>executablePath</code> option with extreme caution. If Google Chrome (rather than Chromium) is preferred, a <a href="https://www.google.com/chrome/browser/canary.html" target="_blank" rel="noopener noreferrer">Chrome Canary</a> or <a href="https://www.chromium.org/getting-involved/dev-channel" target="_blank" rel="noopener noreferrer">Dev Channel</a> build is suggested. In <code>puppeteer.launch([options])</code>, any mention of Chromium also applies to Chrome.
