backbone.jsHow can I use Backbone.js to make a synchronous fetch request?

Backbone.js provides a sync method which can be used to make synchronous fetch requests. It can be used to create, read, update, and delete models in an application. To make a synchronous fetch request, you can use the following code:

var MyModel = Backbone.Model.extend({
    urlRoot: '/mymodel'
});

var myModel = new MyModel();
myModel.fetch({
    async: false
});

This code will make a synchronous fetch request to the /mymodel endpoint. The response data will be stored in the myModel object.

The fetch method takes an options object as an argument. The async option can be set to false to make the request synchronous.

Code explanation

• MyModel - This is the model class. It has a urlRoot property which sets the endpoint for the fetch request.
• myModel - This is an instance of the MyModel class.
• fetch - This is the method used to make the fetch request.
• options - This is an object containing options for the fetch request.
• async - This is a boolean option which determines whether the request is synchronous or asynchronous.
