It is said that Backbone handles all the higher level abstractions, while jQuery or similar libraries work with the DOM, normalize events and so on..
Could someone pleas
Backbone is a MV* framework while jQuery is a DOM toolkit.
The main features of an MV* application are routing, data binding, templates/views, models, and data access. Backbone could dependant on jQuery partially.
jQuery is a solid API for querying the DOM with extensive browser support and a vibrant community. It comes with event handling, deferred objects, and animations.
// When any  tag is clicked, we expect to see '
 was clicked' in the   console.
$( "p" ).on( "click", function() {
console.log( "
 was clicked" );
});
