[Joris PZ]

I feel stupid several times a day, especially when I manage to forget one of the functional collection tricks like mapKeys. Part of the job 🙂

[oday]

yes, it is a trick

[oday]

i was totally not used to seeing that function

[oday]

thanks a lot friend

By the way, when you're doing mileageValuesToYears.keys.zipWithNext(), you are basically zipping together random keys. A normal map and its keyset isn't ordered.

[oday]

correct yes
