Unexpected token on response.writeHead

Unexpected token on response.writeHead

Problem

When running the following code in Node.JS it produces some error but I cant understand why

var http = require("http"), fs = require("fs");

function onRequest(request, response){
        request.on("end", function(){
                fs.readFile("test.txt", "utf-8", function(error, data){
                        response.writeHead(200, {"Content-Type", "text/plain"});
                        data = parseInt(data) + 1;
                        fs.writeFile('test.txt', data);
                        response.end("This page was refreshed "+data+" times!\n");
                });
        });
}

http.createServer(onRequest).listen(8080);

Here are the errors I get:

/home/dev/nodeplay/files.js:7

Solution

This part: {"Content-Type", "text-plain"} is an invalid object.

Do you mean:

{"Content-Type": "text-plain"}
