Please, can you give more explantions on the role of the argument in the each method ?
I don't understand how the argument work in the each method.

Array#each (or the each method) basically goes over each item in an array and does whatever code is in the code block. The argument passed in is the current item in the array that is being worked on. An easy way to get a better understanding is to go into IRB and put in the following code:
nums = [1,2,3,4,5,6,7,8,9,10] nums.each do |num| puts num end
What that does is it will run the
puts method on each number since you're passing them in one at a time as the argument. Hopefully this helps.
