Interesting facts about JSON

  • Difficulty Level : Basic
  • Last Updated : 16 Jan, 2019

JSON or JavaScript Object Notation is a lightweight format for transporting and storing data. JSON is used when data is transferred from a server to a web page. This language is also characterized as weakly typed, prototype-based, dynamic, and multi-paradigm.

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

Here are some interesting facts about JSON:

  • JSON was derived from JavaScript but by 2017 many programming languages include code to invoke and parse JSON-format data. It is a language-independent data format. For JSON, the official Internet media type is application/json. The filenames of JSON use the extension .json.
  • The first person to specify and popularize the JSON format was Douglas Crockford. The acronym came into existence at the State Software, a company co-founded by Crockford and the other members in March 2001.
  • In a children’s digital asset trading game project named Cartoon Orbit a precursor to the JSON libraries was used at for the Cartoon Network, which used a browser side plug-in with a copyrighted messaging format to influence DHTML elements.
  • The JavaScript running in the browser decrypts the JSON string and shows the product details in the page for the user.
  • The jQuery JavaScript library includes few useful methods, for example getJSON() and parseJSON(). These make it easy to accept JSON-encoded data via Ajax requests.
  • For JSON text, the official MIME type is “application/json” and this have been adopted by many of the modern implementations.
  • JSON grew out of a need for stateless, real-time server-to-browser communication protocol without making use of any browser plugins such as the dominabt methods like Flash or Java applets, which are used in the early 2000s.
  • There is expanding support for JSON through the use of many lightweight third-party packages. The list of supported languages includes ColdFusion, Perl, Python, Rebol, ActionScript, E, Java, JavaScript, C, C#, ML, Objective CAML, PHP, Lua and Ruby.
  • The simplicity of JSON has resulted in its global use, especially as a substitute to XML in Ajax. An advantage of JSON over XML as a data interchange format is that it is much simpler to write a JSON parser.
