# oneByOne.js

Array.forEach replacement for async operations

oneByOne.js allows you to loop over a array and execute some async operations. Method itself returns a promise and resolves into an array of results of executions just like `Promise.all`.

Difference from `Promise.all` is, your actions are executed sequentially and you have access to previous results.

Example 1: 

```js

require('onebyonejs');

['a', 'b', 'c', 'd'].oneByOne(function(element, index, results, previousResult) {

  return new Promise(function (done) {

    fetch('www.google.com/?q=' + element)

    .then(function(response) { return response.text() })

    .then(function(responseText) {

      done(responseText); 

    }) 

  });

});

``` 

Example 2: 

```js

require('onebyonejs');

['a', 'b', 'c', 'd'].oneByOne(async (element, index, results, previousResult) => {

    const response = await fetch('www.google.com/?q=' + this)

    const responseText = await response.text();

    return responseText;

});

``` 

It does not export anything, so you just include it.
