If I remember correctly, React and Vue started off as more view-layers than anything else, and popularized the idea of 1-way, isolated components. Angular and Ember had always been all-in-one-heavy frameworks with 2-way bindings by default, and “partials” similar to components but state was intrinsically shared in a MVC paradigm.

Vue in itself is just like React, a rendering library with reactivity.

Vue also provides official batteries like Vuex and VueRouter but you do not really need those to use Vue.
