# callbag-to-iterable

Convert a synchronous pullable callbag source to an Iterable.

`npm install callbag-to-iterable`

## example

Convert an Iterable to a synchronous pullable callbag, apply some operators, then convert back to Iterable and consume it with a `for of` loop:

```js

const {forEach, fromIter, take, map, pipe} = require('callbag-basics');

const toIterable = require('callbag-to-iterable');

function* range(from, to) {

  let i = from;

  while (i <= to) {

    yield i;

    i++;

  }

}

const result = pipe(

  fromIter(range(40, 99)), // 40, 41, 42, 43, 44, 45, 46, ...

  take(5), // 40, 41, 42, 43, 44

  map(x => x / 4), // 10, 10.25, 10.5, 10.75, 11

  toIterable

);

for (let x of result) {

  console.log(x)

}

// 10

// 10.25

// 10.5

// 10.75

// 11

```
