Is there a way by looking the code a site to understand if backbone is used in it. Is a single page app.https://taxibeat.com/

typically a library requires library code to be included, like when pages include jquery. First place is to check the head of the HTML document. For frameworks like backbone/angular, you can probably tell by looking at the DOM elements and looking for custom properties. Angular for example uses ng-* as the prefix.
