I disagree that its frameworks all the way down. There is a distinction between frameworks and libraries. React, Angular, et al are frameworks in the truest sense of the word.

Things like jQuery and Underscore on down to stdio.h are libraries. You can pick and choose from what they contain but they're not so tightly coupled that they get in your way.

They're a tool belt with tools that do one thing and do it really well. Frameworks are like having a tool belt with a hammer that also has a saw on the end but in order to use the saw you have to grab the screwdriver even if you're not actually using it.
