I thought you meant it was a known best practice in JavaScript in general. I know have kept an eye on React and it's intriguing, but I have yet to hack with it because I mostly work in an ecosystem of libraries that have an alternative, which is pretty much literally an independent implementation of Backbone.View, but without coupling to the rest of Backbone like Model or Events. I generally deploy these modules together to the web, and I want to keep the file size of my base layer small. I think React looks cool but I haven't gotten to the point where I want to send my users 30k more code when It does seem promising for new projects. I hope to give it a go soon.
