Will rendering multiple views in Backbone happen synchronous or asynchronous?

Question

Let me start by saying this is a theoretical question thus I cannot provide you with any code.

I'm thinking about a Backbone structure where multiple views get rendered on one page. Every view contains a render function with one or more API calls which have responsetimes that can be fast or slow.

I'm wondering if we have view order A, B, C, D and A's data is responding slowly from the server, will this block the rendering/data retrieval of B, C and D when I loop through those views to render, or will it initialize the render function of A don't care about it and initialize the render function B?

I tried to write this as clearly as possible but if you have any questions just ask.

UPDATE: Some time passed and I found a way to link these all together. I worked with a jQuery deferred and used the pipe method to pipe these deferreds together. Source: https://api.jquery.com/deferred.pipe/

I tested this by setting up a JSFiddle and found out that Backbone doesn't care about loading slow requests. It just renders another view if that's called. For anyone's information
