I've briefly done stuff with that concept. It deals with asynchronous operations. So let's say you make an API call to my.api/longOperation. You're expecting some data back but there's no telling how long it will take. So instead of returning some JSON object, you return a Promise that eventually some data will be returned. So when longOperation finally finishes 60 seconds later on the back end, it gives you that data you were promised.Anyone familiar with reactive programming? (i.e.: futures, promises, Rx extensions, etc.)
shyts hard to follow.
