Tuple Unpacking in Map Operations

Question

I frequently find myself working with Lists, Seqs, and Iterators of Tuples and would like to do something like the following,

val arrayOfTuples = List((1, \"         


        

Answer 1

Why don't you use

arrayOfTuples.map {t => t._1.toString + t._2 }

If you need the parameters multiple time, or different order, or in a nested structure, where _ doesn't work,

arrayOfTuples map {case (i, s) => i.toString + s} 

seems to be a short, but readable form.
