What is Backbone Js?

Backbone is the JavaScript library whose demand is growing because of the structure it provides to the web applications. It has amazing features that attract the developers such as rich API of enumerable functions, models with key-value binding and custom events, declarative event handling and many more. The utmost service of Backbone is that it doesn't mix up business logic with your user interface i.e., it helps you to keep your business separate from your user interface. Because it is very hard to implement the change when these two are entangled.

Why choose Backbone.js?

Lightweight: The main advantage of the backbone is that it is very lightweight. In case you possess a brown-field app or a legacy and you want to clean up the messy jQuery code then Backbone is perfect for you. If you are the beginner and you haven't still decided about which framework you should adopt then you should select Backbone without any hesitation. It is very small and hence lightweight. It is more like a library rather than a framework. It is very helpful in the clean things up, refactor old code, get some more modularity around the things you're doing.

Maintainability by following conventions: If you are tired of doing so much coding then Backbone is far good for you because it provides a common coding style. At, it is clearly seen that Backbone.js is especially helpful to manage the clean code base in spite of having a lot of people co-operating on the code. The conclusion here is that the more you hold with the Backbone.js the less you have to go through the coding. Moreover, these codes are more standardized and readable.

Event-driven communication: One of the major advantages of Backbone.js is that it supports event-driven communication. Although it is quite easy to build a simple and small app on jQuery. But when the project grows it is quite tough to handle it. Its callbacks and declaration become very complicated and spread all over the place. As a result, codes become difficult to read and confusing. Backbone.js makes it ease with the help of an event-driven communication between models and views. As the Backbone events build on the top of the regular DOM events it makes the mechanism more extendible and flexible.

Performance Control: Another astonishing feature of the Backbone.js is its performance. It gives you a lot more control over the performance in comparison with the other framework especially in the case of mobile. So, if you are comfortable in the JavaScript and you are worried about the performance obstacle which may arise as the result of the framework's two-way data binding then Backbone is what you need.

Cons of Backbone JS

Large projects: Backbone.js is the best fit for small projects, but upon large projects, it is better to choose other projects.

Two-way binding: Unlike Angular.js, the backbone doesn't support two-way data winding. Here, you can use data binding plugins or you have to link the views and models with the lengthy codes.

Community: Backbone doesn't have a large community like the other famous frameworks. It is far behind them. Also, its documentation is not as good as others.

Templates: In backbone.js, one should have to choose the template by own self. This is good for those who have a good knowledge of template engines. But it is quite difficult to make a choice for the users who don't know a bit about them.
