Function json

json<ParsedJSONObject>(url, init?): Promise<ParsedJSONObject | undefined>
Fetches the json file at the specified input URL and returns it as a Promise of a parsed JSON object.

If init is specified, it is passed along to the underlying call to fetch.

If the server returns a status code of 204 No Content or 205 Reset Content, the promise resolves to undefined.
