I ran across this anecdote about how people don't know (or acknowledge?) the existence of the index argument of Array.map. This is a link to the manuscript of the well regarded book on JS FP techniques "Javascript Allonge". The book was linked elsewhere in these comments. The index arg is not mentioned!
