## 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 \[(await worker.executionContext()).evaluateHandle(pageFunction, ...args)\](\#executioncontextevaluatehandlepagefunction-args).

<b>Signature:</b>

```typescript
evaluateHandle(pageFunction: Function | string, ...args: any[]): Promise<JSHandle>;
```

## Parameters

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

<b>Returns:</b>

Promise&lt;[JSHandle](./puppeteer.jshandle.md)<!-- -->&gt;

Promise which resolves to the return value of `pageFunction`<!-- -->.
