Neo-Async




  





  

  

  

  

  

  

  



Neo-Async is thought to be used as a drop-in replacement for [Async](https://github.com/caolan/async), it almost fully covers its functionality and runs [faster](#benchmark).

Benchmark is [here](#benchmark)!

Bluebird's benchmark is [here](https://github.com/suguru03/bluebird/tree/aigle/benchmark)!

## Code Coverage

![coverage](https://raw.githubusercontent.com/wiki/suguru03/neo-async/images/coverage.png)

## Installation

### In a browser

```html

```

### In an AMD loader

```js

require(['async'], function(async) {});

```

### Promise and async/await

I recommend to use [`Aigle`](https://github.com/suguru03/aigle).

It is optimized for Promise handling and has almost the same functionality as `neo-async`.

### Node.js

#### standard

```bash

$ npm install neo-async

```

```js

var async = require('neo-async');

```

#### replacement

```bash

$ npm install neo-async

$ ln -s ./node_modules/neo-async ./node_modules/async

```

```js

var async = require('async');

```

### Bower

```bash

bower install neo-async

```

## Benchmark

[Benchmark: Async vs Neo-Async](http://suguru03.hatenablog.com/entry/2016/06/10/135559)

### How to check

```bash

$ node perf

```

### Environment

* Darwin 17.3.0 x64

* Node.js v8.9.4

* async v2.6.0

* neo-async v2.5.0

* benchmark v2.1.4

### Result

The value is the ratio (Neo-Async/Async) of the average speed.
