npm install callbag-from-iter

example

Convert an Iterable:

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

const source = fromIter([10, 20, 30, 40]);

source(0, iterate(x => console.log(x)); // 10
                                        // 20
                                        // 30
                                        // 40

Convert an Iterator:

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

const source = fromIter([10, 20, 30, 40].entries());

iterate(x => console.log(x))(source); // [0,10]
                                      // [1,20]
                                      // [2,30]
                                      // [3,40]
