   *
   * The only difference between {@link Page.evaluate | page.evaluate} and
   * `page.evaluateHandle` is that `evaluateHandle` will return the value
   * wrapped in an in-page object.
   *
   * If the function passed to `page.evaluateHandle` returns a Promise, the
   * function will wait for the promise to resolve and return its value.
   *
   * You can pass a string instead of a function (although functions are
   * recommended as they are easier to debug and use with TypeScript):
   *
   * @example
   *
   * ```ts
   * const aHandle = await page.evaluateHandle('document');
   * ```
   *
   * @example
   * {@link JSHandle} instances can be passed as arguments to the `pageFunction`:
   *
   * ```ts
   * const aHandle = await page.evaluateHandle(() => document.body);
   * const resultHandle = await page.evaluateHandle(
   *   body => body.innerHTML,
   *   aHandle,
   * );
   * console.log(await resultHandle.jsonValue());
   * await resultHandle.dispose();
   * ```
   *
   * Most of the time this function returns a {@link JSHandle},
   * but if `pageFunction` returns a reference to an element,
   * you instead get an {@link ElementHandle} back:
   *
   * @example
   *
   * ```ts
   * const button = await page.evaluateHandle(() =>
   *   document.querySelector('button'),
   * );
   * // can call `click` because `button` is an `ElementHandle`
   * await button.click();
   * ```
   *
   * The TypeScript definitions assume that `evaluateHandle` returns
   * a `JSHandle`, but if you know it's going to return an
   * `ElementHandle`, pass it as the generic argument:
   *
   * ```ts
   * const button = await page.evaluateHandle<ElementHandle>(...);

   * const aHandle = await page.evaluate(() => 2);
