batch.js

function batch(cb, maxSize, timeout) {
    var queue = [];
    var timer;

    var flushQueue = function() {
        cb(queue);
        queue = [];
    };

    return function enQueue(msg) {
        if (timer) {
            window.clearTimeout(timer);
        }
        queue.push(msg);
        if (queue.length > maxSize) {
            flushQueue();
        } else {
            timer = window.setTimeout(function() {
                flushQueue();
            }, timeout);
        }

    };
};

/////////////////
// basic usage
/////////////////

var info = batch(function(a) { console.log(a); }, 10, 1000);

//console.log 0 to 10
// then after timeout console.log 11 to 14
for(var i = 0; i < 15; i++) {
   info('msg '+i);
}
