Isn't Backbone the closest analogy to React, in that it tries to be modular enough to be as small/big as needed -- as opposed to a full MVC-ish framework like Angular and Ember?
Backbone is an elegant library but I think its popularity and ecosystem were on a decline even before Walmart -- which was one of the biggest corporate contributors (e.g. Thorax [0]) -- did a complete overhaul in 2016 to React [1]
