# 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&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;

## Example


```ts
const tweetHandle = await page.$('.tweet .retweets');
expect(await tweetHandle.evaluate(node => node.innerText)).toBe('10');
```
