You can access any element in your array in O(1). I think it is faster to loop through as well, but I'm not so sure about that.

The drawback is that appending / removing elements at the beginning of the array is O(n).

When it comes to interacting with the collections I mostly use the loop / seq macros, which I believe are pretty similar to Common Lisp. Ofc you also have map / filter / reduce.
