ES6 syntax is “new” but worth highlighting a few parts:
For learning react - I found the react toutrial useful to get started.
lastly, you might have have heard we recently merged redux - I found the following free online courses (each episode is about 2-5 minutes) really worth the time: https://egghead.io/courses/getting-started-with-redux
On the day to day, I also started to use prettier which I see as a anti bikeshedding tool for syntax, whitespaces etc.
I personally also like using Jest for testing which we now also use in the SUI.
comments, suggestions or questions are very welcomed
