This week I want to cover a topic that I feel has become an important part of any developer’s toolkit: the ability to load and manipulate JSON feeds from other sites via AJAX. Many sites are sharing data using JSON in addition to RSS feeds nowadays, and with good reason: JSON feeds can be loaded asynchronously much more easily than XML/RSS. This article will cover the following:
- What is JSON?
- Why does JSON matter?
- How do we use JSON in a project?
We’ll also use our newfound skills with JSON at the end of this project to build a quick app that loads photos from Flickr without requiring a page refresh.
