Evaluators

• iterator()
• reduce()
• run()
• step()
• transduce()

Generators & iterators

• asAsyncIterable()
• concat()
• events()
• raf()
• range()
• repeatedly()
• sidechain()
• source()
• zip()

Combinators

• merge()
• mult()
• pubsub()
• sync()
• syncRAF()

Transducers

• comp()
• filter()
• map()
• mapcat()
• multiplex()
• multiplexObj()
• partition()
• take()
• throttle()
• throttleTime()

Reducers
