Node.js Simple Server JavaScript

Question

I just started last week learning JavaScript and Node.js. Before that I developed with Java WebObjects and VB.NET. I just want to learn it for my self.

My brain is hurting after this week because of closures and other JavaScript stuff.

And now the question. To create a simple Node server I always found some code like this.

var http = require("http");

http.createServer(function(request,response) {
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}).listen(3000);

Is there any difference if I would write the code like this?

var http = require("http");


var serverCallback = function(request, response) {
    response.writeHead(200, {'Content-Type': 'text/plain'});
    response.write("Hello World");
    response.end();
}

var server = http.createServer(serverCallback);
server.listen(3000);

For me this is more readable. But I'm not really sure that its exact the same.

Answer 1

There is no difference in functionality. Use whatever style you like.

在这种情况下，唯一的区别是变量的分配方式，昨天在HN https://news.ycombinator.com/item?id=7672131中找到了
