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
