## ElementHandle.$eval() method
This method runs `document.querySelector` within the element and passes it as the first argument to `pageFunction`. If there's no element matching `selector`, the method throws an error.
If `pageFunction` returns a Promise, then `frame.$eval` would wait for the promise to resolve and return its value.
Signature:
```typescript
$eval(selector: string, pageFunction: EvaluateFn | string, ...args: SerializableOrJSHandle[]): Promise;
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| selector | string | |
| pageFunction | [EvaluateFn](./puppeteer.evaluatefn.md) \| string | |
| args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)\[\] | |
Returns:
Promise<ReturnType>
## Example
```js
const tweetHandle = await page.$('.tweet');
expect(await tweetHandle.$eval('.like', node => node.innerText)).toBe('100');
expect(await tweetHandle.$eval('.retweets', node => node.innerText)).toBe('10');
```
