The Backbone ecosystem

In the five years that Backbone has existed, its popularity has resulted in the development of hundreds of related third-party libraries. In addition, numerous other general-purpose libraries have been released, which can also be of great value to a Backbone developer. While we don't have room to explore these libraries in depth, this chapter will provide you with a preview of each library so that you can identify the ones that would be most beneficial to you.

As we cover the libraries in this chapter, keep in mind that for each library that we preview, there exist several (and sometimes several dozen) competing libraries that we didn't feature. While we could try to list every available library in each category, such a list would quickly become out of date, so instead we've chosen to focus only on the most popular offerings. If any of the libraries in this chapter strike you as useful, we strongly recommend searching the Internet to see what other similar libraries...
