The document defines functions for mapping, filtering, reducing and other common functional operations on lists, vectors and maps in Clojure. It defines functions like vmap to map a function over a vector, filter to filter a collection based on a predicate function, and vreduce to reduce a vector using a function. It also defines some predicate functions like tiene-dos-elementos? to check if a collection has two elements. Examples are provided applying these functions to sample inputs.
