Still poorly

2024-02-29

Probably just some musings...

Well... I'm still not well. It's approaching 3 weeks and my consistent cough is at least shifting form again away from rattly chesty discomfort to something on the drier side. Great. I've spent a lot of time doing nothing, and I'm tired of it. So perhaps today things can happen again.

I just spotted this code in my drum machine mockup:

<script setup>
const tracks = ref([
    { steps: 24 },
    { steps: 8 },
    { steps: 4 }
]);
const maxSteps = tracks.value.reduce(
    (acc, cur) => Math.max(acc, cur.steps),
    0
);
</script>

And I wondered to myself... Why am I running max over the whole array like that in a reduction, rather than pulling the items out into an array, and destructuring that array into the Math.max call?

const tracks = [23, 53, 4, 8];
const maxSteps = Math.max(...tracks);

Is this a thing I can do? ... Yes! It's little things like this that make programming actually feel fun. Identifying a tiny puzzle and solving it. Repeat that enough times and you can build something spectacular.

So, in vue terms code terms we end up with this:

<script setup>
const tracks = ref([
    { steps: 24 },
    { steps: 8 },
    { steps: 4 }
]);
const maxSteps = computed(
    () => Math.max(
        ...tracks.value.map(({ steps }) => steps)
    )
);
// maxSteps = 24 👍
</script>

I just made some small tweaks to bind the track step length to a number input. So far so good.

This has felt like a bit of a warmup for the day. I might come back to it later on, but I should probably take a peek at my client work.
