Deferred Execution Queue

app.js

var deferredExecutionQueue = [];
function deferExecution(func, delayMS) {
    deferredExecutionQueue.push({ func: func, time: new Date().getTime() + delayMS });
}
setInterval(function() {
    if (!deferredExecutionQueue.length)
        return;
    if (deferredExecutionQueue[0].time < new Date().getTime()) {
        var deferred = deferredExecutionQueue.pop();
        deferred.func();
        deferred.func = deferred.time = null;
    }
}, 500);

Usage:
deferExecution(myFunction, 1000);

Instead of:
setTimeout(myFunction, 1000);
or, the frequently used:
setTimeout(function() { myFunction(); }, 1000);
