I'm fairly new to using promises in javascript. I specifically work in nodeJS and up to this point I've done mostly everything using callbacks. Now I'm working with a library that does everything primarily through promises and they recommend using When, but after doing some research I found Q which looks more popular. I believe its compatible with whichever library I use that follow the Promises/A+ standards – which they both do.
Is any one actually better than the other? If so, why?
