I'm pretty sure erlangs :array is just a skin over tuple, so it's ~O(1) but not contiguous. might be O(log n) for dynamic arrays. The only truly array datatype in Erlang is :atomics

Erlang tuples are contiguous in memory for primitive values https://blog.edfine.io/blog/2016/06/28/erlang-data-represent...

Array doesn't guarantee to be put into a single tuple. It might be nested.
