## Use Enum.map or Enum.each
@spec map(t(), (element() -> any())) :: list()
Returns a list where each element is the result of invoking fun on each
corresponding element of enumerable.
For maps, the function expects a key-value tuple.
## Examples
iex> Enum.map([1, 2, 3], fn x -> x * 2 end)
[2, 4, 6]
iex> Enum.map([a: 1, b: 2], fn {k, v} -> {k, -v} end)
[a: -1, b: -2]
@spec each(t(), (element() -> any())) :: :ok
Invokes the given fun for each element in the enumerable.
Returns :ok.
## Examples
Enum.each(["some", "example"], fn x -> IO.puts(x) end)
"some"
"example"
#=> :ok
