Graph
a: {---1---2---3---4}
b: {---------x------}
takeUntil(a, b): {---1---2--------}
Signature
Stream a -> Stream b -> Stream a
Usage
const takeUntil = require('flyd/module/takeuntil')
const source = flyd.stream()
const end = flyd.stream()
const result = takeUntil(source, end)
source(1)(2)
result() // 2
source(3)
result() // 3
end(true)
result() // 3
source(4)(5)
result() // 3
