Array merge in elixir
I have 2 arrays: a1 can be any combination of value or nil like that
a1 = [1,nil,3]
and array 2 the same
a2 = [4,2, nil]
How do I combine them together in a way that if a2 contains a value its value will take
so, in the above array the result will be: [4,2,3]

There are no arrays in Elixir.

You can probably use
Enum.zip_with/2. The following should do if I understand you correctly (a2takes precedennce unless it isnil):Enum.zip_with([a1, a2], fn [a, nil] -> a; [_, b] -> b end)
