# 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
|
|
|
|
| Parameter | Type | Description |
|
|
| --- | --- | --- |
|
|
| pageFunction | Func \| string | |
|
|
| args | Params | |
|
|
|
|
**Returns:**
|
|
|
|
Promise<Awaited<ReturnType<Func>>>
|
|
|
|
## Example
|
|
|
|
|

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