callbag-latest-batch

--------------------

[Callbag](https://github.com/callbag/callbag) operator that turns a listenable source into a pullable source, emiting all the data since the last request batched within an array, if any.

Much like [callbag-latest](https://github.com/krawaller/callbag-latest) but one that collects all the interim data.

## example

```js

const interval = require('callbag-interval')

const sample = require('callbag-sample')

const pipe = require('callbag-pipe')

const latestBatch = require('callbag-latest-batch')

const randomStream = pipe( // random numbers generated every second

  interval(1000),

  map(() => Math.floor(Math.random()*100))

)

const submitActionStream = pipe( // collected into arrays every five seconds

  interval(5000),

  sample(latestBatch(randomStream)) 

)

```
