+/**
+ * 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 PageEmittedEvents.FrameAttached}
+ * - {@link PageEmittedEvents.FrameNavigated}
+ * - {@link PageEmittedEvents.FrameDetached}
