The Rise and Rise of JSON
JSON has taken over the world. Today, when any two applications communicate with each other across the internet, odds are they do so using JSON. It has been adopted by all the big players: Of the ten most popular web APIs, a list consisting mostly of APIs offered by major companies like Google, Facebook, and Twitter, only one API exposes data in XML rather than JSON.1 Twitter, to take an illustrative example from that list, supported XML until 2013, when it released a new version of its API that dropped XML in favor of using JSON exclusively. JSON has also been widely adopted by the programming rank and file: According to Stack Overflow, a question and answer site for programmers, more questions are now asked about JSON than about any other data interchange format.2
