how can I turn two arrays into a map whose keys are from one array and values are from the other?

[marstran]

So the first element from the first array are the key for the first element of the second array?

[oday]

it seems it’s done like this

val map = friends.associateBy({it.facebookId}, {it.points})

[oday]

but this works on a list

[oday]

what I have is an object with 2 lists

[oday]

and yes @marstran like you said first

[marstran]

Please give an example input and the expected output.

[marstran]

Ok, in that case you could do list1.zip(list2).toMap().

[marstran]

But beware, it will drop elements if the lists have different lengths.

[oday]

no they are symmetrical

[oday]

in fact the result from the API should’ve been pairs

[oday]

not 2 lists, lol
