How to add an element from another array to each element of an array in Ruby?

Question

ruby

There are two arrays

array1 = Array.[]("a", "b", "c", "d", "e")
array2 = Array.[]("1", "2", "3", "4", "5")

It is necessary to bring the output to the following form:
"//1a or //2b or //3c or //4d or //5e"
Started like this

a = array2.all.map {  | w|  "//"  + w + ....... }
a.join(" or ")

The output of one array turns out to be normal, but I don’t know how to add elements of the second array in turn to each element of the array.
The number of elements in the arrays is the same.

Answer 1

a = array1.map.with_index{|n, i| '//' + array2[i] + n}.join(' or ')
