Fun Fact
The JSON format itself is derived from JavaScript object notation. Escaping rules originated from JavaScript string handling in the early days of web development.
Historical Context
JSON was formalized in the early 2000s and standardized in RFC 4627. As web applications grew more complex, escaping became critical to prevent parsing errors, injection issues, and data corruption. Today, JSON escaping remains a core practice in software engineering across APIs, databases, and distributed systems.
