Common JSON Errors and How to Resolve Them
JSON strictly adheres to RFC 8259 specifications. According to developer error logs, over 78% of syntax failures stem from three common issues:
1. Trailing Commas in Objects or Arrays
JSON does not permit a comma after the final key/value pair or array element.
{ "status": "ok", } { "status": "ok" }
2. Single Quotes Instead of Double Quotes
JSON standard requires all keys and string values to be wrapped in double quotes "...".
{ 'user': 'Alex' } { "user": "Alex" }
