Exploring the Backbone.js framework
Before starting with the example's application, we should check out the main features of the framework. Sometimes, it's good to know what is going on under the hood. So, let's dive in.
Recognizing the framework dependency
Most of the software that we use nowadays is built on top of other libraries or tools. Normally, they are called dependencies.
