Full Stack JavaScript Techdegree Graduate 17,901 Pointsunable to edit the www file
Not a question. Sharing a problem and workaround that I experienced...
In the Treehouse workspace I renamed www to www.js, but when attempting to save the file I got a "workspace connection lost" message then when the workspace was restored the edit was not saved. At another time the workspace would not display www.js file's contents the tab.
Eventually I discovered that I could edit and save if I renamed the file to www.txt.
Don't know if it's OS related. I'm on Mac OS 10.14

var http = require('http');

var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
/**

var server = http.createServer(app);
/**

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);

function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
