First I implemented a printError function

that will display the message from the error object.

I used a try catch statement in case if the URL is malformed.

Remember, if a malformed URL is entered,

the error will be thrown immediately and not emitted.

In the catch block, I called the print error function for the malformed error.

Then I checked the status code was okay or 200.

Here, I created an error message with a human readable status message.

Remember, STATUS_CODES object is only on HTTP, not HTTPS.

I've also included a readable query, adding spaces back in to the query.

The code for

the readable query is up here, because I may need it for other errors later on.

Next I catch any thrown errors by the JSON parser.

Finally if the query doesn't return a location because it's spelt wrong, or

the place doesn't exist, we want to return a sensible error message.

Let's see this in action.

Type node app.js 90210.

And then a location.

And then somewhere fictional.

And we get that sensible error message.

Cool.

Great work, you've come a long way.

You should be really proud of yourself.

You've created two command line applications that go out on to

the Internet and retrieve information.

Now that you've worked with two API endpoints, you can use any.

The possibilities are endless.

Why not make a command line utility that goes out to Twitter and

brings back the latest tweets from your favorite JavaScript developer?

Or get the latest stock prices for your favorite tech company?

Or a command line application that converts currencies?

I encourage you to practice more to really solidify the concepts.

Looking at the documentation and other solutions isn't cheating.

They're aids for your learning.

Until next time, keep practicing.
