How do I pipe a single number to get a list?

Question

I have a single element/number that I am piping to Enum.into([]) but Elixir throws ** (Protocol.UndefinedError) protocol Enumerable not implemented for 90

90 |> Enum.into([])

v = 65
v |> Enum.into([]) Enumerable not implemented for 65

Answer 1

Enum.into/2 expects an Enumerable as the first argument, hence the error.

To pipe a Single Element into a list, use List.wrap

65 |> List.wrap
