    @floatright If I understand the promises right I don't have to use them if I fine with simple callbacks, is that right?

    Wait till your projects gets big, you'll spend half the time in understanding the source of callback function of callback function of callback function of.......

    Hint - use promises ;)

    You never understand Javascript. That's how it works.

    @Divisionbyzero Well, not really. Promises are a different use case. In fact promises themselves can accept callbacks. Anyway, if you are using jquery for network requests, you're already using callbacks in promises ;)

    XMLHttpRequests aren't promised by default. It's just event based. Libraries exist to wrap then and use promises though.

    @vzqzac nice, but the browsers seems to support this poorly.

    @Divisionbyzero yes, this does actually come with ES.. 7 I guess? So it will take its time to be available everywhere, but node LTS supports it now and as a developer more​ focused in back end I'm really excited :D

    Oh. I somehow missed the part where you were talking about jQuery based queries.
