I'm excited because this means two things for me and my QOL:
1. Faster editor.
2. Some of the missing features from go-plus will now be merged to the master branch of the package since it depended on React being default in the editor. Really excited. :) https://atom.io/packages/go-plus
It seems like a lot of big projects are switching from Ember or Angular to React, or are choosing it for new projects. I think that's a good thing.
