## 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)`
|
|
|
|
<b>Signature:</b>
|
|
|
|
```typescript
|
|
evaluateHandle<HandlerType extends JSHandle = JSHandle>(pageFunction: EvaluateHandleFn, ...args: SerializableOrJSHandle[]): Promise<JSHandle>;
|
|
```
|
|
|
|
