Jeremy Ashkenas

Guido van Rossum

Correct Answer : Jeremy Ashkenas

Explanation :

Backbone.js is a JavaScript library with a RESTful JSON interface and is based on the model–view–controller application design paradigm. Backbone is known for being lightweight, as its only hard dependency is on one JavaScript library, Underscore.js, plus jQuery for use of the full library.

It is designed for developing single-page web applications, and for keeping various parts of web applications (e.g. multiple clients and the server) synchronized. Backbone was created by Jeremy Ashkenas, who is also known for CoffeeScript and Underscore.js.

Initial release : October 13, 2010
