Iterating through a list
I have a list say
x = ["23gh", "56kh", "97mh"]
I would like to pass each element to Val in each iteration.
Say, in iteration 1 -------- Val = "23gh"
iteration 2 -------- Val = "56kh"
iteration 3 -------- Val = "97mh"
With Enum.at I can pass a specific index but not a set of indices. Any idea how to do it or if there is any other alternative to do this.

x = ["23gh", "56kh", "97mh"]forcomprehension might help:Enum.mapimplementation:If you need to iterate with index, then
Enum.with_indexmight be combined with the above ones.The official documentation is here:

As I have exactly pointed out, it would be a loop within a loop. Also,
Enum.zip/2requires equal number of elements in both list to have the same number of elements as result. Here the user has to construct the list, which would render another loop to construct it.
