# WebWorker.evaluateHandle() method

The only difference between `worker.evaluate` and `worker.evaluateHandle` is that `worker.evaluateHandle` returns in-page object (JSHandle). If the function passed to the `worker.evaluateHandle` returns a `Promise`, then `worker.evaluateHandle` would wait for the promise to resolve and return its value. Shortcut for `await worker.executionContext()).evaluateHandle(pageFunction, ...args)`

**Signature:**

```typescript
class WebWorker {evaluateHandle<Params extends unknown[], Func extends EvaluateFunc<Params> = EvaluateFunc<Params>>(pageFunction: Func | string, ...args: Params): Promise<HandleFor<Awaited<ReturnType<Func>>>>;}
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | Func \| string | Function to be evaluated in the page context. |
|  args | Params | Arguments to pass to <code>pageFunction</code>. |

**Returns:**

Promise&lt;[HandleFor](./puppeteer.handlefor.md)&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;&gt;

Promise which resolves to the return value of `pageFunction`.
