JSON is a key/value data structure for JavaScript, but it's useful across languages due to the number of libraries. It typically looks like: { "hello": "world" } Tny converts this JSON into a (usually, but not always) smaller form that's faster to traverse and encode/decode. Tny's alternative, BSON, is being used by MongoDB [1], so that might be a good place to learn more. [1] http://www.mongodb.org/ http://www.mongodb.org/
