const uniqueStations = [...new Set(array)]; (handler.js, line 117)
wow is this like destructuring and a constructor? Nice!!! please show us how it's done!

In src/scripts/sortData.js there are a couple of thing names in mapping functions:

 const inboundTrains = inbound.map(train => {
    const thing = {
      timeToStation: timeConverter(train.timeToStation),
      lineName: train.lineName,
      destinationName: train.destinationName
    };
    return thing;
  });

Just a small thing, but it's worth taking a moment to think about the names when you're writing code, because they're easy to forget to come back to! It's pretty good elsewhere though, so this is just a little detail. 😄

The clock was a neat addition - you have really thought through the user's needs

According to Lighthouse accessibility checks, your buttons do not have accessible names:

"
Failing Elements

button#submit-button.input-submit-button
button#refresh-button.refresh-button
"

I personally

Perhaps you could add ARIA labels to make it more accessible?

You could try modularsing your sortData function!

Really clean, modularized, and understandable! You've achieved a lot in a very short time and should be proud! Very impressive!

In the future you can (and will, at least in your client projects) use it along with issues, so that you have a visual overview of them. Just an FYI though!

You have some, great!! Even if there aren't a lot, it's always great when you have managed to write some tests in this short amount of time.

It would be great to get some Supertest in there too, but no stress!

Also, Tap-Bunny. Enough said. 👏👏👏

Love. It.

P.s. I totally added it to my homepage.

This should definitely be included in your presentation, including how you implemented it!

As a user, I'm unsure if the refresh button does anything when I press it. If the dataest hasnt updated, it would be nice to see a message appear to the tune of "Latest train times already displayed"

In your readme goals, you ticked off test coverage - what utility did you use?

TFF should be TTF :)

In your src/scripts/handler.js handleDefaultStation there is a redundant sortData call:

{
        res.writeHead(200, { "Content-Type": "application/json" });
        sortData(response); //This one doesn't actually do anything since it isn't assigned anywhere!
        const result = sortData(response);
        res.end(JSON.stringify(result));
      }

Again, just small details, but your project is very well written so you're all making me work to find issues! 😂

Fantastic!! Really great to see on your readme that you did both on the first day too!!
