pubnub storage and playback history function

is it possible to execute publish function before history function.

PUBNUB_demo.publish({
    channel: 'demo_tutorial',
    message: {"color":"blue"}
});

PUBNUB_demo.history({
    channel : 'demo_tutorial',
    count : 100,
    callback : function(m){console.log(m)}
});

for some reason history function executes before publish function is it possible to change that so publish function is executes always first

JavaScript is asynchronous so history is called before publish function completes. To do this properly, you need to call history inside of the publish success callback like this:

PUBNUB_demo.publish({
    channel: 'demo_tutorial',
    message: {"color":"blue"},
    success: function(){
        PUBNUB_demo.history({
            channel : 'demo_tutorial',
            count : 100,
            callback : function(m){console.log(m)}
        });
    }
});
