# Next
Because asynchronous calls suck out your brain without a proper async handler. This one is just 4 lines yet it solves a huge issue.
### Install
```config
npm install nextjs
```
### How it works?
1. Create a `Next Instance`: `var next = new Next(2, finish)`
2. Then you call `next()` as many times as you specified in the `count`. In this example it is *2*.
3. After `next` was called *2 times*, the `finish` function will be called.
### Example
```javascript
// Include
var Next = require('nextjs');
// CREATE a Next Instance
var next = new Next(2, finish);
// Log Start
console.log('start');
// Will happen after 5 seconds passed
setTimeout(function(){ console.log('A'); next(); }, 5000);
// Will happen after 2 seconds passed
setTimeout(function(){ console.log('B'); next(); }, 2000);
// Will happen in the end after 5 seconds passed
function finish(){ console.log('finished'); }
// output result
// 0 second => start
// 2 second => B
// 5 second => A
// 5 second => finished
```
## Next parameters
- **count**: the number of times you will have to call the `next()` instance. `required` `integer`
- **finish**: finishing callback `required` `function`
## Key features
- It's just 4 lines - `0.16kb`
- Easy to use
- Its part of `dietjs`
