JS Arrow Function

can anyone help me replace anonymous functions with ES6 arrow functions

http.createServer(function(request, response) { let urlObj = url.parse(request.url, true, false) console.log(' ============================') console.log("PATHNAME: " + urlObj.pathname) console.log("REQUEST: " + ROOT_DIR + urlObj.pathname) console.log("METHOD: " + request.method) let receivedData = ''   //attached event handlers to collect the message data  request.on('data', function(chunk) { receivedData += chunk }) //event handler for the end of the message  request.on('end', function() { console.log('received data: ', receivedData) console.log('type: ', typeof receivedData) //if it is a POST request then echo back the data.  if (request.method == "POST") { let dataObj = JSON.parse(receivedData) console.log('received data object: ', dataObj) console.log('type: ', typeof dataObj) //Here we can decide how to process the data object and what  //object to send back to client.  //FOR NOW EITHER JUST PASS BACK AN OBJECT  //WITH "text" PROPERTY   //TO DO: return the words array that the client requested  //if it exists   console.log("USER REQUEST: " + dataObj.text) let returnObj = {} returnObj.text = 'NOT FOUND: ' + dataObj.text  for (title in songs) { //console.log(title + " : " + dataObj.text);  if (title === dataObj.text) { returnObj.text = 'FOUND'  returnObj.wordArray = songs[title] } } //object to return to client  response.writeHead(200, { 'Content-Type': MIME_TYPES['json'] }) response.end(JSON.stringify(returnObj)) //send just the JSON object  } if (request.method == "GET") { //handle GET requests as static file requests  let filePath = ROOT_DIR + urlObj.pathname  if (urlObj.pathname === '/') filePath = ROOT_DIR + '/index.html'   fs.readFile(filePath, function(err, data) { if (err) { //report error to console  console.log('ERROR: ' + JSON.stringify(err)) //respond with not found 404 to client  response.writeHead(404); response.end(JSON.stringify(err)) return  } response.writeHead(200, { 'Content-Type': get_mime(filePath) }) response.end(data) }) } }) }).listen(3000) console.log('Server Running at PORT 3000 CNTL-C to quit') console.log('To Test') console.log('http://localhost:3000/example1.html')
