Elixir does not do anything better at IO than other languages.

They do have a really compelling conccurent processing story though, which is what most people mean when they say it's better at IO.

What's "other languages"?

IO lists, which are the foundation of anything that build a string incrementally, are managed with vectored IO syscalls out of the box (readv/writev), which you'd have to handle yourself in most other languages, or resort to allocating and endless memory copying which Erlang is able to avoid.
