Fill all three blanks to create a server that responds with JSON and listens on port 8080.

Node.js

const server = http.[1]((req, res) => {
  res.statusCode = [2];
  res.setHeader('Content-Type', [3]);
  res.end(JSON.stringify({ message: 'Hi' }));

Common Mistakes

Using wrong method name, status code, or content type for JSON response.

The server is created with createServer, status code 200 means OK, and content type 'application/json' tells the browser to expect JSON data.
