property ServerResponse.prototype.statusMessage
Usage in Deno
```typescript import { ServerResponse } from "node:node__http.d.ts"; ```When using implicit headers (not calling `response.writeHead()` explicitly),
this property controls the status message that will be sent to the client when
the headers get flushed. If this is left as `undefined` then the standard
message for the status code will be used.
```js
response.statusMessage = 'Not found';
```
After response header was sent to the client, this property indicates the
status message which was sent out.
