 Nested Routing is the general idea of coupling segments of the URL to component hierarchy and data. React Router's nested routes were inspired by the routing system in Ember.js circa 2014. The Ember team realized that in nearly every case, segments of the URL determine:
 
 - The layouts to render on the page
-- The code split JavaScript bundles to load
 - The data dependencies of those layouts
 
 React Router embraces this convention with APIs for creating nested layouts coupled to URL segments and data.
