nextjs

Next Module - A low-level asynchronous function caller

Because asynchronous calls sucks out your brain without a proper async handler.

How it works?

1. Create a Next Instance: var nextInstance = new Next(2, finish)
2. Then you call nextInstance() as many times as you specified in the count. In this example it is 2.
3. After nextInstance was called 2 times, the finish function will be called.

Example: How to handle multiple functions in asynchronous manner?

	// CREATE a Next Instance
	var next = new Next(2, finish);
	console.log('start');
	
	// This will happens at 5000 milliseconds
	setTimeout(function(){ console.log('A'); next(); }, 5000); 
	
	// This happens at 2000 milliseconds
	setTimeout(function(){ console.log('B'); next(); }, 2000); 
	
	// this happens at the end at 5000 milliseconds
	function finish(){ console.log('finished'); } 
	
	// output
	// 0ms 	  => start
	// 2000ms => B
	// 5000ms => A
	// 5000ms => finished
