What is JSON (JavaScript Object Notation)?
JSON is a lightweight, language-agnostic data interchange format built on key-value pairs and ordered lists, serving as the industry standard for REST APIs, cloud databases, and configuration structures.
Frequent JSON Syntax Traps
- Trailing Commas: Trailing commas after the last item in arrays or objects are strictly prohibited by the JSON specification.
- Single Quotes: Keys and string values must strictly utilize double quotes (
"key"). - Unquoted Keys: JavaScript permits unquoted object keys, but valid JSON mandates them.
