 I am Pawan Shah from ThoughtWorks. So what I am trying to do is, I am trying to build a service which calls multiple systems which hold unique profile data and club this into one profile object which can be utilized by any other system which requires profile data. So what I am trying to understand is this asynchronous programming not just how can I utilize this and call these various systems. So this was kind of eye-opener for me. There was a lot of myths I had because result and what I learned was coffee script sucks. You should use JavaScript for asynchronous programming not coffee script. That was my big learning I had which I had to do some major changes in my progress. But yeah now it's a bit easy now. At least I know how can I achieve this so-called integrated profile and prank.
