* ```ts
* import puppeteer from 'puppeteer';
*
* (async () => {

*
* @example
* This example logs a message for a single page `load` event:
*
* ```ts
* page.once('load', () => console.log('Page loaded!'));
* ```
*

 /**
  * @remarks
  *
  * 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>(...);
