### `name`

`name` is an optional property of a `DurableObjectId`, which returns the name that was used to create the `DurableObjectId` via [`DurableObjectNamespace::idFromName`](/durable-objects/api/namespace/#idfromname). This value is undefined if the `DurableObjectId` was constructed using [`DurableObjectNamespace::newUniqueId`](/durable-objects/api/namespace/#newuniqueid).
`name` is an optional property of a `DurableObjectId`, which returns the name that was used to create the `DurableObjectId` via [`DurableObjectNamespace::idFromName`](/durable-objects/api/namespace/#idfromname). This value is undefined if the `DurableObjectId` was constructed using [`DurableObjectNamespace::newUniqueId`](/durable-objects/api/namespace/#newuniqueid). This value is also undefined within the `ctx.id` passed into the Durable Object constructor (see [GitHub issue](https://github.com/cloudflare/workerd/issues/2240) for details).

```js
const uniqueId = env.MY_DURABLE_OBJECT.newUniqueId();
