4,779 PointsQuick Question about loops and iterations
Why a change in variables inside an .each iteration does not change the variable in the original array, while a simillar change inside a loop does change the original array?
Thank you!

Attached you will find the documentation of ruby: https://ruby-doc.org/core-2.2.0/Array.html#method-i-map
hope it is helpful!
Greetings!
