Hey @emrancu, thank you for contributing to ReactPHP! ❤️

The React\Http\Message\Response::json() method alongside the other methods (HTML/plaintext/XML) were introduced in #439 and we use these factory methods throughout our documentation and examples to make them more readable. These methods are entirely optional and do not replace the Response constructor. This means, instead of using the json() method, we can also use:

$response = new React\Http\Message\Response(
 React\Http\Message\Response::STATUS_OK,
 [
 'Content-Type' => 'application/json'
 ],
 json_encode(
 ['name' => 'Alice'],
 JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES | JSON_PRESERVE_ZERO_FRACTION
 ) . "\n"
);

This way you can directly use the Response constructor in order to adapt the status code. So I'm wondering how much is gained by the suggested change, what do you think?
