Error handling - show on page to notify user

[helenzhou6]

Great error handling and use of error-first callbacks!

It looks like in your handler.js file you are sending back an error message and appropriate status code:

        res.writeHead(500, { "Content-Type": "application/json" });
        res.end(JSON.stringify({ error : "Can't get the latest articles" }));

Here

But in the front end the error message is not being used and displayed to the user:

PaGiToNi/public/index.js

Lines 44 to 46 in 7a5fea2

	if (error) {
	console.log(error, "something went wrong");
	return;

I would somehow try and display the error (such as there has been a server error) to the user rather than console.log
