Tip: you can benefit from a modern list manipulation api with dash.el and the newer seq.el, that iterates over all sequences (lists, vectors, strings) (but does not have anaphoric macros).
Vector
see seq.el that iterates over sequences, and so vectors.

Sequence
sequence type is the union of two other Lisp types: lists and arrays. While array has four types, all one-dimensional: strings, vectors, bool-vectors, char-tables.
