node.js - When trying to execute an JavaScript file gives me an: SyntaxError: unexpected token ) -

during path on creating chat application, trying create app.js file till came across easy/novice silly syntaxerror don't think wrong it, still causes issues me progress onwards, tried adding additional parentheses, brackets or semicolons. wouldn't resolve :/

this app.js file:

var express = require('expres'),  //now in express no longer create http server automatically     //app variable function bundles in express     //for socket.io need http server object so, need create manually      app = express(),       //create variable called "server".     //requires http module, "createserver" (creates server) , pass data onto "app" variable.      server = require('http').createserver(app),      //then need create socket functionality.     //create variable called "io".     //the variable "io" requires "socket.io" , need make "listen".     //so why need http server, parameter of "listen".     //socket.io listens http server object.     //so need pass "server"      io = require('socket.io').listen(server);      //next: need tell server on port listen on.     //pick available port, in case "3000" within option below.  server.listen(3000);  //after setting server //we need create "route". //right can't access pages.  //and express makes somethings easier. //makes routing bit easier. //we going use variable "app" . "get" function variable equals "express framework". //then set root directory "/" forward slash sign. //so that's first parameter on client trying access. //and without express have "function" "http request" , "http response" parameters.  app.get('/'), function(req, res){  //and declare "http response" , . "sendfile" because, going create file called "index.html" want client whenever goes "localhost:3000". //then create "directory name" + "index.html" web page.      res.sendfile(__dirname + '/index.html'); }); //then check if works within command prompt execute command: "node app.js" //which run javascript file. 

and here result when input node app.js command! i've installed socket.io executing command npm install socket.io still wouldn't solve issue. :/

any ideas how can resolve issue, cause don't seem have syntax errors in opinion tbh :/

thanks in advance.

app.get structure is:

app.get(path, callback [, callback ...]) 

correct code is:

app.get('/', function(req, res){  //and declare "http response" , . "sendfile" because, going create file called "index.html" want client whenever goes "localhost:3000". //then create "directory name" + "index.html" web page.      res.sendfile(__dirname + '/index.html'); }); 

more express routing here.
