JSON Basics
Who invented json format?
Douglas Crockford invented the JSON format in the early 2000s while working at State Software. He discovered that JavaScript's object literal notation could be used as a lightweight data interchange format, simpler than XML. Crockford specified JSON and promoted its adoption, registering json.org in 2002 to provide documentation and specifications. While JavaScript's object notation existed earlier, Crockford formalized the subset suitable for data exchange and established the standard. He intentionally kept JSON minimal, excluding features like comments to maintain simplicity. The format gained rapid adoption due to its elegance and practicality. JSON was standardized as RFC 4627 in 2006 and later updated as RFC 8259. Crockford's invention revolutionized web development, making data exchange simpler and more efficient, fundamentally shaping modern web APIs and application development.
