Change value of array element which is being referenced in a .each loop?

Question

How do I get the following to happen: I want to change the value of an array element which is being referenced between pipe characters in a .each loop.

Answer 1

The each method never changes the object it works on.

You should use map! method instead:

x = %w(hello there world)
x.map! { |element|
   if(element == "hello")
       "hi" # change "hello" to "hi"
   else
       element
   end
}
puts x # output: [hi there world]
