# PropertyPartNode

Represents a property assignment (e.g. `.value="${value}"`).

## Signatures

```ts
export declare class PropertyPartNode {
    readonly _tag: "property";
    readonly name: string;
    readonly index: number;
    constructor(name: string, index: number);
}
```

## Why

Native element properties remain distinct from serialized attributes.

## Ownership and lifetime

The part stores metadata; the mounted part owns its local property writes.

## Constructor

Creates native property syntax.

## Property: _tag

Native-property discriminant.

## Property: _tag: Why

Selects property assignment rather than attribute serialization.

## Property: _tag: Ownership and lifetime

Immutable AST metadata.

## Property: index

Interpolation index producing the property value.

## Property: index: Why

Locates the producer for one direct property update.

## Property: index: Ownership and lifetime

Immutable scalar metadata; the render Scope owns the producer.

## Property: name

Native property name.

## Property: name: Why

Identifies the exact property target on the native element.

## Property: name: Ownership and lifetime

Retained string metadata.

## Examples

```ts
import { PropertyPartNode } from "@typed/template/Template"

const part = new PropertyPartNode("value", 0)
```
