Node.js: Syntax Error on exporting

This is really fundamental... I am just getting started with Node.js. I have a simple module server.js ``` var http = require("http"); function start() { function onRequest() { console.log("Request received"); response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello World"); response.end(); } http.createServer(onRequest).listen(8888); console.log("Server has started..."); } export.start = start; ``` and it's being called from index.js as follows ``` var server = require("./server"); server.start(); ``` but running `node index.js` gives me this! ``` $ node index.js d:\SourceRepo\node-sample\server.js:15 export.start = start; ^^^^^^ SyntaxError: Unexpected reserved word at Module._compile (module.js:437:25) at Object.Module._extensions..js (module.js:467:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:362:17) at require (module.js:378:17) at Object.<anonymous> (d:\SourceRepo\node-sample\index.js:1:76) at Module._compile (module.js:449:26) at Object.Module._extensions..js (module.js:467:10) at Module.load (module.js:356:32) ``` How to sort this out? I am a newbie to JavaScript!
