Merge stream delay

As the following code:

const mixStream = flyd.merge(stream1, stream2)

const mixScan = flyd.scan((o, n) => { return {
  a: scanStream1(),
  b: scanStream2()
} }, {
  a: 0,
  b: 0
}, mixStream)

I expect mixScan to show the result from both stream 1 and 2 updates. I did, but with a 1 step behind. Given stream1 <-- [1,2,3] then stream2 [4,5,6], this is the result for mixScan

mixScan	stream1	stream2
{a:0, b:0}
{a:0, b:0}	1
{a:1, b:0}	2
{a:2, b:0}	3
{a:3, b:0}		4
{a:3, b:4}		5
{a:3, b:5}		6

Okay I looked at your App.jsx file since I happened to have time.

https://github.com/meepeek/meiosis-react-example/blob/master/src/App.js#L12

Change this line from

const mixUpdate = flyd.merge(componentA.update, componentB.update)

to

const mixUpdate = flyd.merge(componentA.listener, componentB.listener)

And things will work like you expect

I take it by the thumbs up this issue is resolved, I’ll close it, but feel free to reopen if this did not help.
