Backbone.js fetch Collection

The Backbone.js fetch Collection is used to fetch the set of models from the server for collection. When the models are returned models are merged with the existing models. If we want to reset all the models and form fill new models we use { reset: true } option of this method which resets the collection. 

Syntax: 

collection.fetch( options );

Parameters: 

• options: This option hash takes success and error callbacks which will be in case of status of response from the server.
