Key Differences
JSON (JavaScript Object Notation) is a lightweight, human-readable data format easily parsed natively in modern JavaScript applications. XML (eXtensible Markup Language) uses custom tags and attributes, leading to a verbose and bulkier payload structure.
• Parsing: JSON uses native JavaScript compiler optimizations. XML requires dedicated DOM or SAX parser objects. • Size: JSON payloads are smaller, reducing transit bandwidth. • Meta-data: XML supports attributes and schemas (XSD), which helps enforce strict enterprise data structures.
