append!

.adds x to acc and returns acc

cat

A high-performance combining fn that yields the catenation of the reduced values. The result is reducible, foldable, seq...

drop

Elides the first n values from the reduction of coll.

filter

Retains values in the reduction of coll for which (pred val) returns logical true. Foldable.

flatten

Takes any nested combination of sequential things (lists, vectors, etc.) and returns their contents as a single, flat ...

fold

Reduces a collection using a (potentially parallel) reduce-combine strategy. The collection is partitioned into groups o...

foldcat

Equivalent to (fold cat append! coll)

folder

Given a foldable collection, and a transformation function xf, returns a foldable collection, where any supplied reducin...

map

Applies f to every value in the reduction of coll. Foldable.

mapcat

Applies f to every value in the reduction of coll, concatenating the result colls of (f val). Foldable.

monoid

Builds a combining fn out of the supplied operator and identity constructor. op must be associative and ctor called with...

reduce

Like core/reduce except: When init is not provided, (f) is used. Maps are reduced with reduce-kv

reducer

Given a reducible collection, and a transformation function xf, returns a reducible collection, where any supplied reduc...

remove

Removes values in the reduction of coll for which (pred val) returns logical true. Foldable.

take

Ends the reduction of coll after consuming n values.

take-while

Ends the reduction of coll when (pred val) returns logical false.
