Any JSON value.

**Signature:**

```typescript
export type AnyJson = boolean | number | string | null | undefined | JsonArray | JsonObject;
```
**References:** [JsonArray](https://imqueue.org/api/core/latest/core.jsonarray/), [JsonObject](https://imqueue.org/api/core/latest/core.jsonobject/)

## Remarks

`undefined` is accepted by the type for ergonomics but is not preserved by serialization — `undefined` properties are silently dropped when a message is sent.
