2,539 Pointswhats the difference between what Jason has in the video and this code?
1 In the video he has the code 2 array = [0, 1, 2, 3, 4, 5] 3 array.each do |item| 4 item = item + 2 5 puts "The current item + 2 is #{item}." 6 end
But on like 4 he has item = item + 2
would it be doing the same thing if I were to put it as
item += 2
or would this have a different meaning entirely?

2,539 PointsI did try it, but I feared maybe it was similar to puts and print where they are completely different but for what I was using them for they showed up the same. Thanks for the answer!
