## ElementHandle.$$eval() method
This method runs `document.querySelectorAll` within the element and passes it as the first argument to `pageFunction`<!-- -->. If there's no element matching `selector`<!-- -->, the method throws an error.
If `pageFunction` returns a Promise, then `frame.$$eval` would wait for the promise to resolve and return its value.
<b>Signature:</b>
```typescript
$$eval<ReturnType extends any>(selector: string, pageFunction: Function | string, ...args: unknown[]): Promise<ReturnType>;
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| selector | string | |

| args | unknown\[\] | |
<b>Returns:</b>
Promise&lt;ReturnType&gt;

<div class="feed">
<div class="tweet">Hello!</div>
<div class="tweet">Hi!</div>

const feedHandle = await page.$('.feed');
expect(await feedHandle.$$eval('.tweet', nodes => nodes.map(n => n.innerText)))
