# JSHandle.evaluate() method
|
|
|
|
This method passes this handle as the first argument to `pageFunction`. If `pageFunction` returns a Promise, then `handle.evaluate` would wait for the promise to resolve and return its value.
|
|
|
|
**Signature:**
|
|
|
|
```typescript
|
|
class JSHandle {
|
|
evaluate<
|
|
Params extends unknown[],
|
|
Func extends EvaluateFunc<[this, ...Params]> = EvaluateFunc<
|
|
[this, ...Params]
|
|
>
|
|
>(
|
|
pageFunction: Func | string,
|
|
...args: Params
|
|
): Promise<Awaited<ReturnType<Func>>>;
|
|
}
|
|
```
|
|
|
|
## Parameters
|

|
|
| ------------ | -------------- | ----------- |
|
|
| pageFunction | Func \| string | |
|
|
| args | Params | |
|
|
|
|
**Returns:**
|
|
|
|
Promise<Awaited<ReturnType<Func>>>
|
|

const tweetHandle = await page.$('.tweet .retweets');
