He is saying that Node is not a JavaScript framework. It is technically a back end scripting language. So maybe you would do well with a better umbrella term like skills or tools.
Noted – use of terminology could've been more accurate, but for the purpose of this article we tried to keep it quite simplified. Perhaps the wrong approach with regards to accuracy.
What were your thoughts on the broader points of the post?
I agree with it in terms of generally desired skill sets. Angular rose to prominence very quickly and Node has had a very steady grassroots climb. Backbone has been on the decline for a while now. I don't think React has the klout to really become a commonplace skill. We will see what happens with Angular after 2.0 though.
