# JSHandle.evaluateHandle() method

```typescript

|
||
|
|
evaluateHandle<
|
||
|
|
Params extends unknown[],
|
||
|
|
Func extends EvaluateFunc<[this, ...Params]> = EvaluateFunc<
|
||
|
|
[this, ...Params]
|
||
|
|
>
|

**Returns:**
|
||

## 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.
