question: how would you do something specific only on last index while doing a collection.map{ }?

[Paul Griffith]

use mapIndexed and check if the first parameter is the collection's size...if the collection is actually sized

You can do something like:

yourList
  .mapIndexed { (i, it) ->
    if (i == yourList.lastIndex) foo()
    else bar()
  }
