You generally only listen and wait for the "end" event on the request body
if you care about the request body. In both these examples you're not
listening for the request "data" events, so I don't think the "end" event
(part of the same stream interface) is interesting.
Also I noticed that one example calls res.write(...) ; res.end(), while the
second does just res.end(...). In node it's better to just call
res.end(...) for your last or only response body chunk.
I would write these two examples as:
var http = require("http");
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.end("Hello World");
});
server.listen(8888);
