# callbag-take

Callbag operator that limits the amount of data sent by a source. Works on either pullable and listenable sources.

`npm install callbag-take`

## example

On a listenable source:

```js

const interval = require('callbag-interval');

const forEach = require('callbag-for-each');

const take = require('callbag-take');

const source = take(3)(interval(1000));

forEach(x => console.log(x))(source);    // 0

                                         // 1

                                         // 2

```

On a pullable source:

```js

const fromIter = require('callbag-from-iter');

const forEach = require('callbag-for-each');

const take = require('callbag-take');

function* range(from, to) {

  let i = from;

  while (i <= to) {

    yield i;

    i++;

  }

}

const source = take(4)(fromIter(range(100, 999)));

forEach(x => console.log(x))(source);    // 100

                                         // 101

                                         // 102

                                         // 103

```
