purrr

purrr applies a function to each element of a list or vector and collects the results, similar in spirit to base R's apply family but with more consistent, predictable behavior. Its map() function always returns a list, while variants like map_dbl() return a vector of a specific type, making the expected output explicit. It fits naturally with the pipe operator and tidyverse style, letting you iterate without writing explicit loops.
