Fun Fact
XML predates JSON by several years and was originally designed for document-centric data exchange, whereas JSON emerged later to optimize lightweight machine-to-machine communication.
Historical Context
XML became a W3C standard in 1998 and quickly dominated enterprise data interchange. JSON was introduced in the early 2000s as a simpler alternative aligned with JavaScript ecosystems. Today, both formats coexist, with XML remaining essential in legacy systems, financial messaging, and document workflows.
