Tryggvi Gylfason: This will flow your mind - JSConf Iceland 2016

This talk is about flow, a static type-checker for JavaScript which is developed and maintained by Facebook. We have been using flow extensively at QuizUp for half a year now and it's been a great success in a big JS codebase. In this talk I will answer the following questions: What is it? Why use it? What can it do? What can't it do? Lastly I will go over lessons learned and our experience with using flow.
