->listclj

(->list mapper-fn col)

Returns a new [[java.util.List]] containing the result of applying mapper-fn to each item in col. Returns an unmodifiable list. Note: This will usually be faster than (mapv mapper-fn col) because: - This function allocates a new [[java.util.ArrayList]] in the exact (.size col) size, and then fills it with the mapped values. - If the underlying collection is not a Clojure sequence, then mapv will first convert it to a Clojure sequence and then map over it. This function will not do that.
