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

	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

	// 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
