Is el having a ref or jquery reference ? code snippet below

Question

this.$el = el instanceof Backbone.$ ? el : Backbone.$(el);

this.el = this.$el[0];

What does Backbone.$ mean in the code snippet below ? is it the Jquery reference to backbone ?

Check the answer to the duplicate, that covers `Backbone.$` quite well. Basically, `Backbone.$` is jQuery's `$` without any possible namespace or naming issues. — mu is too short, Jul 17 '17 at 16:03

update: el instanceof Backbone.$ mean check if el is jQuery/zepto object or not. Backbone.$ is backbone variable and used as alias for jQuery/zepto.

from the doc http://backbonejs.org/#View-dollar

If jQuery is included on the page, each view has a $ function that runs queries scoped within the view's element. If you use this scoped jQuery function, you don't have to use model ids as part of your query to pull out specific elements in a list, and can rely much more on HTML class attributes. It's equivalent to running: view.$el.find(selector)

So this means that. If the jquery selector of an html element (this.$el) is there in the view with backbone as a reference (Backbone.$) then the jquery reference of that element is it's reference (el and not this.$el ) else it's a jquery reference of the Backbone view ? – Harshit Juneja Jul 17 '17 at 09:55
it still isn't very clear to me. – Harshit Juneja Jul 17 '17 at 09:55
Can you take me further with this ? – Harshit Juneja Jul 17 '17 at 10:23
