pull combine latest 

Combine the latest values from many streams. The algorithm waits until every stream has emitted a value, then emits a new array whenever one of the streams has more data.

install

$ npm install pull-combine-latest

example

``js
var S = require('pull-stream')
var combineLatest = require('pull-combine-latest')

S(
// pass an array of streams
combineLatest([S.values([1,2,3]), S.values(['a','b','c'])]),
S.log()
)

S(
// or pass streams as arguments
combineLatest(S.values([1,2,3]), S.values(['a','b','c'])),
S.log()
)

/*
output:

[1,'a']
[2,'a']
[2,'b']
[3,'b']
[3,'c']

*/


// new data is emitted as soon as it is received, so sync data will always
// be emitted before async data
S(
combineLatest(S.values([1,2,3]), asyncValues(['a','b','c'])),
S.log()
)
/*
[1,'a']
[2,'a']
[3,'a']
[3,'b']
[3,'c']
*/


// object map
S(
combineLatest({
a: S.values([1,2,3]),
b: S.values([1,2,3])
}),
S.log()
)
/*
{ a: 1, b: 1 }
{ a: 2, b: 1 }
{ a: 2, b: 2 }
{ a: 3, b: 2 }
{ a: 3, b: 3 }
