# JSHandle class

Represents a reference to a JavaScript object. Instances can be created using [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md).

Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely [disposed](./puppeteer.jshandle.dispose.md). JSHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.

Handles can be used as arguments for any evaluation function such as [Page.$eval()](./puppeteer.page._eval.md), [Page.evaluate()](./puppeteer.page.evaluate.md), and [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md). They are resolved to their referenced object.

#### Signature:

```typescript
export declare abstract class JSHandle<T = unknown>
```

## Remarks

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `JSHandle` class.

## Example

```ts
const windowHandle = await page.evaluateHandle(() => window);
```
