Neo-Async
Neo-Async is thought to be used as a drop-in replacement for Async, it almost fully covers its functionality and runs faster.
Benchmark is here!
Bluebird's benchmark is here!
Code Coverage
Installation
In a browser
<script src="async.min.js"></script>
In an AMD loader
require(['async'], function(async) {});
Promise and async/await
I recommend to use Aigle
.
It is optimized for Promise handling and has almost the same functionality as neo-async
.
Node.js
standard
$ npm install neo-async
var async = require('neo-async');
replacement
$ npm install neo-async
$ ln -s ./node_modules/neo-async ./node_modules/async
var async = require('async');
Bower
bower install neo-async

Benchmark
How to check
$ 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.
