# isDocumentFragment

Checks if a rendered node is a `DocumentFragment`.

## Signatures

```ts
export declare function isDocumentFragment(node: Rendered): node is DocumentFragment;
```

## Why

Fragment output is distinguished from persistent Wire ranges before insertion.

## Ownership and lifetime

The check borrows the native DocumentFragment; it does not insert its
children or consume the fragment.

## Examples

```ts
import { isDocumentFragment } from "@typed/template/Wire"

const result = isDocumentFragment(document.createDocumentFragment())
```
