property Http2ServerResponse.prototype.statusCode
Usage in Deno
```typescript import { Http2ServerResponse } from "node:node__http2.d.ts"; ```When using implicit headers (not calling `response.writeHead()` explicitly),
this property controls the status code that will be sent to the client when
the headers get flushed.
```js
response.statusCode = 404;
```
After response header was sent to the client, this property indicates the
status code which was sent out.
