**Backbone `noConflict`** displays the original value of a Backbone object. Moreover, it allows you to store reference to a backbone. `Backbone.noConflict()` returns the Backbone object to its original value, which can be used to keep a local reference to any Backbone. This is very useful when a user intends to instill Backbone on a third-party website, but doesn't want to compromise any existing Backbone(s).

# Code
```
var sample_backbone=Backbone.noConflict();
```
