perhaps I was being impatient observing a group of web developers and designers trying to jump into a large React project, practically with no prior experience in react (although familiar with Angularjs, html, css, js, dom) - however the fact is that after 3 months of dev, the react codebase turned into an absolute mess - albeit following best practices around branches, testing, pull request reviews, continuous delivery to staging environments etc...

The main issues seemed to do with global state management favored by Redux (hello global variables, I thought we were over you years ago :) ) and tendency to jam html into react components designed as screens, rather than components.
