Backbone.js render View

0 0 1 minute read

Backbone.js is a compact library used to organize JavaScript code. Another name for it is an MVC/MV* framework. If MVC isn’t familiar to you, it merely denotes a method of user interface design. JavaScript functions make it much simpler to create a program’s user interface. Models, views, events, routers, and collections are among the building blocks offered by BackboneJS to help developers create client-side web applications.

View’s Render function is primarily used to create the basic framework for a view and how it will be shown. This function is used to execute some logic that is used to render the template which will construct the view.

Syntax:

view.render()
