Elixir IO List



IO List

  • Binary
  • 0 to 255 Integer
  • IO List

In our example, we created an incremental iodata list with the string “Does mask protect me against COVID-19 virus?” Then we use the IO.write function on that list.


  • IO module has functions that work with IO lists
  • Adding to IO List is O(1) while adding to the regular list is O(n).
