How to determine array element number in a each loop

Ruby
1

Hello all, newbie here.

The title is quite self explanatory: I am in

dummy_array.each do |a|
#code here
end

and I want to know which element (the number n in nth element) of the
dummy_array.

Thanks in advance :slight_smile:

You could just put a counting variable in there:

i = 0

dummy_array.each do |a|
i = i+1
#code here
end

You can also use each_index on the array if you’d like.

or use each_with_index
