how can I replace one single element in an array in ruby?

Question

how can I replace one single element in an array in ruby? so that an array

days=["monday", "tuesday", "wednesday", "jueves"]  #so "jueves" gets replaced by the string "thursday"

thanks

@pguardiario, I've noticed that's an increasingly popular spelling of the day of the week following 'wednesday'. — Cary Swoveland

You an also do...

days.map!{|day| day == "jueves" ? "thursday" : day}

m-p's answer will replace the first occurrence, this will replace all occurrences.

days[3] = "thursday"

Unless you want something more dynamic.
