A Browser is created when Puppeteer connects to a Chromium instance, either through PuppeteerNode.launch or Puppeteer.connect.

BrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method Browser.newPage | Browser.newPage creates a page in the default browser context.

ChromeTargetManager uses the CDP's auto-attach mechanism to intercept new targets and allow the rest of Puppeteer to configure listeners while the target is paused.

ConsoleMessage objects are dispatched by page via the 'console' event.

The Coverage class provides methods to gathers information about parts of JavaScript and CSS that were used by the page.

Dialog instances are dispatched by the Page via the dialog event.

ElementHandle represents an in-page DOM element.

Represents a DOM frame.

A frame manager manages the frames for a given Page | page.

Represents an HTTP request sent by a page.

The HTTPResponse class represents responses which are received by the Page class.

Puppeteer methods might throw errors if they are unable to fulfill a request. For example, page.waitForSelector(selector[, options]) might fail if the selector doesn't match any nodes during the given timeframe.

We use symbols to prevent external parties listening to these events. They are internal to Puppeteer.
