JSON is a workhorse data format of the modern Web. Originating from the JavaScript world, it gained a lot of traction and at the moment it's usually the first choice of a Web developer for a data interchange format. Not only Web - once JavaScript-only, JSON support is now ubiquitous. A lot of languages ship with JSON parsers in the standard libraries, and when it's not the case, surely someone has already built a third party library. In case of Rust, JSON support comes out of the box in the serialize::json module.
