BackboneJS Tutorial - Learn BackboneJS in simple and easy steps using this beginner's tutorial containing basic to advanced knowledge starting from Overview.

I'll give a basic overview of these concepts to nourish your understanding of BackboneJS. They contain all the helpful functions needed to manipulate some piece of data from the persistence layer. When any of its data is modified, Models trigger change events. Consider a Model as a sort of manipulator. Instead of directly interacting with the data from your API, it serves as a layer that allows you easily manipulate every tiny piece of data in a very friendly and fantastic way. Here's a simple case study: Imagine we are in charge of a gift shop and we need to build a database of the gifts that we sell. We need to keep track of the stock of those gifts.

I'll leave you to persist it to a backend or use local Storage. Go ahead and create your app directory. In the root directory, create an index. Also create css, and js folders within the directory. Inside the js directory, go ahead and create the collections, models and views directories. Populate the index. Wilson', avatar: ' We have three template-type scripts. One for displaying the list of employees, another for editing and creating new employees and one for displaying the link for creating new employees.
