It seems like the more I google there are more people who supports Go more than Node for mainly these reasons: simplicity and no callback mess.
Just to let you know I read these links: http://www.quora.com/Node-js/Why-did-Koding-switch-from-Node-js-to-Go http://jordanorelli.com/post/31533769172/why-i-went-from-python-to-go-and-not-node-js
I understand that every language have their own usage so here are my condition. 1) I'm willing to use async to solve the callback nightmare in node. 2) Frontend is iOS so no advantage of having a same language in JS.
What's your 2 cents?
