* @example
* ```
* const aHandle = await page.evaluateHandle('document')

*
* @example
* ```
* 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:
*
* ```
* const button = await page.evaluateHandle<ElementHandle>(...);

* @remarks
*
* This method behaves differently depending on the first parameter. If it's a
* `string`, it will be treated as a `selector` or `xpath` (if the string
* starts with `//`). This method then is a shortcut for
* {@link Page.waitForSelector} or {@link Page.waitForXPath}.
*
* If the first argument is a function this method is a shortcut for
* {@link Page.waitForFunction}.
*
* If the first argument is a `number`, it's treated as a timeout in
* milliseconds and the method returns a promise which resolves after the
* timeout.
*
* @param selectorOrFunctionOrTimeout - a selector, predicate or timeout to
* wait for.
* @param options - optional waiting parameters.
* @param args - arguments to pass to `pageFunction`.
*
* @deprecated Don't use this method directly. Instead use the more explicit
* methods available: {@link Page.waitForSelector},
* {@link Page.waitForXPath}, {@link Page.waitForFunction} or
* {@link Page.waitForTimeout}.

/**
* Causes your script to wait for the given number of milliseconds.
*
* @remarks
*
* It's generally recommended to not wait for a number of seconds, but instead
* use {@link Page.waitForSelector}, {@link Page.waitForXPath} or
* {@link Page.waitForFunction} to wait for exactly the conditions you want.
*
* @example
*
* Wait for 1 second:
*
* ```
* await page.waitForTimeout(1000);
* ```
*
* @param milliseconds - the number of milliseconds to wait.
