`
cljs.user=> (doc nth)
cljs.core/nth
([coll n] [coll n not-found])
Returns the value at the index. get returns nil if index out of
bounds, nth throws an exception unless not-found is supplied. nth
also works for strings, arrays, regex Matchers and Lists, and,
in O(n) time, for sequences.
`
{{Lists}} is a carryover from the Clojure docstring, and likely also is {{regex Matchers}}.
