JSON grew out of a need for a stateless, real-time server-to-browser communication protocol without using browser plugins such as Flash or Java applets, the dominant methods used in the early 2000s. History ĭouglas Crockford at the Yahoo Building (2007) The ECMA and ISO/ IEC standards describe only the allowed syntax, whereas the RFC covers some security and interoperability considerations. That same year, JSON was also standardized as ISO/ IEC 21778:2017. RFC 8259, published in 2017, is the current version of the Internet Standard STD 90, and it remains consistent with ECMA-404. But somehow, 'JAY-sawn' seems to have become more common in the technical community.' Crockford said in 2011, 'There's a lot of argument about how you pronounce that, but I strictly don't care.' Standards Īfter RFC 4627 had been available as its 'informational' specification since 2006, JSON was first standardized in 2013, as ECMA-404. The UNIX and Linux System Administration Handbook states that ' Douglas Crockford, who named and promoted the JSON format, says it's pronounced like the name Jason. The first (2013) edition of ECMA-404 did not address the pronunciation.
