/**
 * Represents a DOM frame.
 *
 * To understand frames, you can think of frames as `<iframe>` elements. Just
 * like iframes, frames can be nested, and when JavaScript is executed in a
 * frame, the JavaScript does not effect frames inside the ambient frame the
 * JavaScript executes in.
 *
 * @example
 * At any point in time, {@link Page | pages} expose their current frame
 * tree via the {@link Page.mainFrame} and {@link Frame.childFrames} methods.
 *
 * @example
 * An example of dumping frame tree:
 *
 * ```ts
 * import puppeteer from 'puppeteer';
 *
 * (async () => {
 *   const browser = await puppeteer.launch();
 *   const page = await browser.newPage();
 *   await page.goto('https://www.google.com/chrome/browser/canary.html');
 *   dumpFrameTree(page.mainFrame(), '');
 *   await browser.close();
 *
 *   function dumpFrameTree(frame, indent) {
 *     console.log(indent + frame.url());
 *     for (const child of frame.childFrames()) {
 *       dumpFrameTree(child, indent + '  ');
 *     }
 *   }
 * })();
 * ```
 *
 * @example
 * An example of getting text from an iframe element:
 *
 * ```ts
 * const frame = page.frames().find(frame => frame.name() === 'myframe');
 * const text = await frame.$eval('.selector', element => element.textContent);
 * console.log(text);
 * ```
 *
 * @remarks
 * Frame lifecycles are controlled by three events that are all dispatched on
 * the parent {@link Frame.page | page}:
 *
 * - {@link PageEvent.FrameAttached}
 * - {@link PageEvent.FrameNavigated}
 * - {@link PageEvent.FrameDetached}
