first
(first ob)
Return an observable that only has the first value of the provided observable. You can optionally pass a predicate and default value.

from
(from v)
Creates an observable from js arrays, clojurescript collections, and promise instance.
from-atom

from-event
(from-event et ev)
Creates an Observable by attaching an event listener to an event target
if-empty
(if-empty default ob)
Emits a given value if the source Observable completes without emitting any next value, otherwise mirrors the source Observable.
ignore
(ignore ob)
Ignores all elements in an observable sequence leaving only the termination messages.
interval
(interval ms)
Returns an observable sequence that produces a value after each period.
last
(last ob)
Return an observable that only has the last value of the provided observable. You can optionally pass a predicate and default value.
mapcat
(mapcat f ob)

merge-all
(merge-all ob)
(merge-all concurrency ob)
Merges an observable sequence of observable sequences into an observable sequence.
merge-map
(merge-map f ob)
Projects each element of an observable sequence to an observable sequence and merges the resulting observable sequences or Promises or array/iterable into one observable sequence.
In other languages is called: flatMap or mergeMap.
merge-scan
(merge-scan f seed ob)
Applies an accumulator function over the source Observable where the accumulator function itself returns an Observable, then each intermediate Observable returned is merged into the output Observable.
race
Create an observable that surfaces any of the given sequences, whichever reacted first.
range
(range b)
(range a b)
Generates an observable sequence that repeats the given element.
reduce
(reduce f seed ob)
Applies an accumulator function over an observable sequence, returning the result of the aggregation as a single element in the result sequence.
retry
(retry ob)
(retry n ob)
Given an optional number of retries and an observable, repeats the source observable the specified number of times or until it terminates. If no number of retries is given, it will be retried indefinitely.
scan
(scan f seed ob)
Applies an accumulator function over an observable sequence and returns each intermediate result. Same as reduce but with intermediate results
scheduler
