iex(1)> [x, y] = ["String1", "String2"] iex(2)> "#{x} #{y}" # "String1 String2"

["String1", " ", "String2"] |> IO.iodata_to_binary # "String1 String2" This will gives some performances boosts as strings not duplicated in memory. Alternative method: iex(1)> IO.puts(["String1", " ", "String2"]) # ...

Enum.join(["String1", "String2"], " ") # "String1 String2"
