Unblock.js

A single function for dead simple asynchronous control flow.

Usage

Include unblock.js on your page and use as shown in the following example:

// this is a blocking function to use in the example below
var sleep = function (seconds) {
    var ms, startTime;
    ms = seconds * 1000;
    startTime = new Date().getTime(); // get the current time
    while (new Date().getTime() < startTime + ms); // hog cpu
    return seconds;
};

// this is a simple reporter function to use in the example below
var report = function(x) { console.log(x); };

/**
 * EXAMPLE
 */

// this is a basic control flow example
unblock(sleep)(2).then(report).after(sleep)(3).then(report);

// since the above is unblocked, this will run first
report(1);
