100% this. To this day the official website still describe itself as a library, and I'm convinced it's completely for marketing reasons, since 'framework' feels heavy and bloated, like Angular or Java Spring, while 'library' feels fast and lightweight, putting you in control.

Framework can be more or less modular, Angular or Ember choose to be 'battery included', while React choose to be more modular, which is simply choosing the other end of the spectrum on the convenience-versus-flexibility tradeoff.

React ostensibly only care about rendering, but in a way that force you to structure your whole data flow and routing according to its rules (lifecycle events or the 'rules of hooks', avoiding mutating data structures); No matter what they say on the official website, that's 100% framework territory.

Lodash or Moment.js, those are actual bona fide libraries, and nobody ever asked whether to use Vue, Angular or Moment.js, or what version of moment-js-router they should use.
