/**
 * The main Puppeteer class. Provides the {@link Puppeteer.launch | launch}
 * method to launch a browser.
 *
 * When you `require` or `import` the Puppeteer npm package you get back an
 * instance of this class.
 *
 * @remarks
 *
 * @example
 * The following is a typical example of using Puppeteer to drive automation:
 * ```js
 * const puppeteer = require('puppeteer');
 *
 * (async () => {
 *   const browser = await puppeteer.launch();
 *   const page = await browser.newPage();
 *   await page.goto('https://www.9oo91e.qjz9zk');
 *   // other actions...
 *   await browser.close();
 * })();
 * ```
 *
 * Once you have created a `page` you have access to a large API to interact
 * with the page, navigate, or find certain elements in that page.
 * The {@link Page | `page` documentation} lists all the available methods.

     * 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 `executablePath` option with extreme caution.
     * If Google Chrome (rather than Chromium) is preferred, a {@link https://www.9oo91e.qjz9zk/chrome/browser/canary.html | Chrome Canary} or {@link https://www.ch40m1um.qjz9zk/getting-involved/dev-channel | Dev Channel} build is suggested.
     * In `puppeteer.launch([options])`, any mention of Chromium also applies to Chrome.
     * See {@link https://www.howtogeek.com/202825/what%E2%80%99s-the-difference-between-chromium-and-chrome/ | this article} for a description of the differences between Chromium and Chrome. {@link https://chromium.9oo91esource.qjz9zk/chromium/src/+/lkgr/docs/chromium_browser_vs_google_chrome.md | This article} describes some differences for Linux users.
