Display EC2 instance costs per month

The EC2 pricing page shows cost per hour, which is pretty much useless. I want cost per month. The following JavaScript, pasted into the browser developer console, modifies the page to show cost-per-month instead.

Array.from(
    document.querySelectorAll('td')
).filter(
    el => el.textContent.toLowerCase().includes('per hour')
).forEach(
    el => el.textContent = '$' + (parseFloat(
        /\d+\.\d+/.exec(el.textContent)[0]
    ) * 24 * 30).toFixed(2) + ' per month'
)
