5,312 Pointstransaction vs transactions and does it being plural matter?
here is a @transactions = [] then when you loop it a loop you don't put transactions you put
@transactions.each do |transaction|
Now... how does Ruby understand transaction vs transactions? as I never typed transaction as a "method".

Treehouse Moderator 145,860 PointsHey Nate,
In the example you provided, transaction (singular) isn't a method. It is a temporary variable that will store the value of each iteration through the transactions (plural) array. Every iteration will store the new value in the temporary variable to be used in which ever way you code. The next iteration will then remove the first value from the temporary variable and store the new value... and so on until the loop has completed going through the array.
transaction (singular) could have been named anything. I've seen some coders use single letters (eg t because that's the first letter of the array name). However, the convention is to name the temporary variable the singular version of the plural name that the array has.
I hope this helps, but it also wouldn't hurt to take a quick review of for loops.
Keep Coding! :)
