First first contact with Elixir

Hello and welcome,

It is the first trick You need learn in Elixir, [8, 9] is strictly equal to ‘\b\t’, but different representation.

‘’ is for charlist, or list of char

Thank you very much.

What should i do to get [[1,2], [8,9], [5,6]] ?

Hello, my first moments in the forum as well, take a look at this documentation link https://elixir-lang.org/getting-started/binaries-strings-and-char-lists.html#charlists

You can inspect like this…

IO.inspect [[1,2], [8,9], [5,6]], charlists: :as_lists
[[1, 2], [8, 9], [5, 6]]

Thank you!

I will leave the sequence and read about charlist.

Thank you!
I just changed the reading sequence and found that solution.

Thank you for your help.

[72, 101, 108, 108, 111, 32, 97, 110, 100, 32, 119, 101, 108, 99, 111, 109, 101]
