Fun Fact
JSON escaping rules originate from JavaScript string literal conventions established in the late 1990s, which were later standardized as part of the ECMAScript specification.
Historical Context
JSON was formalized in the early 2000s as a lightweight data interchange format derived from JavaScript object notation. Escaping mechanisms were introduced to ensure reliable transmission of structured text across network protocols, databases, and distributed systems.
