/**
 * ElementHandle represents an in-page DOM element.
 *
 * @remarks
 * ElementHandles can be created with the {@link Page.$} method.
 *
 * ```ts
 * const puppeteer = require('puppeteer');
 *
 * (async () => {
 *   const browser = await puppeteer.launch();
 *   const page = await browser.newPage();
 *   await page.goto('https://example.com');
 *   const hrefElement = await page.$('a');
 *   await hrefElement.click();
 *   // ...
 * })();
 * ```
 *
 * ElementHandle prevents the DOM element from being garbage-collected unless the
 * handle is {@link JSHandle.dispose | disposed}. ElementHandles are auto-disposed
 * when their origin frame gets navigated.
 *
 * ElementHandle instances can be used as arguments in {@link Page.$eval} and
 * {@link Page.evaluate} methods.
 *
 * If you're using TypeScript, ElementHandle takes a generic argument that
 * denotes the type of element the handle is holding within. For example, if you
 * have a handle to a `<select>` element, you can type it as
 * `ElementHandle<HTMLSelectElement>` and you get some nicer type checks.
