     * 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();
     * ```
     *
