# JSHandle.evaluateHandle() method
This method passes this handle as the first argument to `pageFunction`.
**Signature:**
```typescript
class JSHandle {
evaluateHandle<
Params extends unknown[],
Func extends EvaluateFunc<[this, ...Params]> = EvaluateFunc<
[this, ...Params]
>
>(
pageFunction: Func | string,
...args: Params
): Promise<HandleFor<Awaited<ReturnType<Func>>>>;
}
```
## Parameters
| Parameter | Type | Description |
| ------------ | -------------- | ----------- |
| pageFunction | Func \| string | |
| args | Params | |
**Returns:**
Promise&lt;[HandleFor](./puppeteer.handlefor.md)&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;&gt;
## Remarks
The only difference between `jsHandle.evaluate` and `jsHandle.evaluateHandle` is that `jsHandle.evaluateHandle` returns an in-page object (JSHandle).
If the function passed to `jsHandle.evaluateHandle` returns a Promise, then `evaluateHandle.evaluateHandle` waits for the promise to resolve and returns its value.
See [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md) for more details.
