Question about Node.js servers

From what I've read, 200 is the HTTP status code for success, but how can we write 200 before we know if the program will be successful?var http = require('http'); var server = http.createServer(function(req, res){ res.writeHead(200, {'Content-Type': 'text/plain'}); //What I mean res.end('Hey ninjas!'); }); server.listen(3000);
