Did I recall that someone here had an alternate typings file for ramda that they used?

i feel like I read somewhere that node 6 wasn't LTS yet even though it was even. Something about only the final minor release in the series actually being LTS.

if I have 2 data formats that can be converted into each other, is there a magical FP way of only writing one converter?

@hkrutzer If I understand it correctly you have w formats and function from one to other:

fromFormat1toFormat2 :: format1 -> format2
fromFormat2toFormat1 :: format2 -> format1

and you want to have

toFormat1 :: any -> format1
toFormat2 :: any  -> format2

Bot don't want implement both of them. if that's the case you can write toFormat1 and implement toFormat2 using composition of toFormat1 and fromFormat1toFormat2

toFormat1 = ...
toFormat2 = toFormat1 |> fromFormat1toFormat2

no I have fromFormat1toFormat2 :: format1 -> format2 and don't want to implement fromFormat2toFormat1 :smile:

I think you cant just because you have fromFormat1toFormat2you cant get fromFormat2toFormat1without implementing it.
also i think if fromFormat2toFormat1(fromFormat1toFormat2(format1))) is equivalent to format1, then format1 and format2 are isomorphic

There's a renameKeys function in the Ramda cookbook that might be what you're after.

Date satisfies Ord, right?
Like I can use R.min with Date-types, right?
