Thor Spieker, fellow Betable engineer, on his experience at JSConf 2015:
First off, let me start by saying that this was my first conference ever, and also that I am not actually a front-end JavaScript developer. Day to day, I spend my time building back-end micro-services in GO for Betable, an online gambling platform. I only dabble in JavaScript when I need to work on our externally facing API, which is written in Node.js. Needless to say, I was a little intimidated going to an all-JavaScript conference where every single person there was probably a much better JavaScript developer than I currently am.
It sounds like an amazing event.
