# Sequences

  - [[range]] ; returns a lazy sequence of integers that span a specified range
  - [[repeat]] ; returns an infinite lazy sequence that repeats a value
  - [[repeatedly]] ; returns an infinite lazy sequence of values generated by calls to a given function
  - [[iterate]] ; like repeatedly, but each call to the function takes the previous element as argument
  - [[cycle]] ; returns an infinite lazy sequence that repeats the elements of a collection
  - [[lazy-seq]]

## core sequence functions

  - [[next]] ; like [[clojure_rest|rest]], but returns [[nil]] for sequence of zero or one elements
  - [[nth]] ; like [[get]], but works on sequences
  - [[apply]] ; invokes a function with arguments taken from sequence
  - [[clojure_map|map]] ; returns a lazy sequence produced by invoking a function with arguments from sequences
  - [[reduce]] ; returns result of invoking a function on successive pairs of elements
  - [[reductions]] ; returns a lazy sequence of the intermediate values that would be produced by reduce
  - [[filter]] ; returns a lazy sequence of elements of another sequence for which a condition function returns true
  - [[remove]]
  - [[take]]
  - [[take-last]]
  - [[take-nth]]
  - [[concat]]

---

  - [[interleave]] ; returns a lazy sequence that takes elements from multiple collection round-robin
  - [[interpose]] ; returns a lazy sequence in which a value is inserted in between elements of a sequence
  - [[distinct]] ; returns a lazy sequence in which only the first occurrence of any value is retained
  - [[reverse]] ; returns a list of the elements of a sequence in reverse order
  - [[flatten]] ; returns a lazy sequence containing the elements of a sequence and its nested sequences
  - [[sort]] ; returns a non-lazy sequence of the elements of another sequence in sorted order
  - [[compare]]
