What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format. It is easy for humans to read and write, and easy for machines to parse and generate.
Why format JSON?
- •Readability — Proper indentation makes data structures clear
- •Debugging — Spot errors and understand data quickly
- •Documentation — Clean JSON for API examples
Common JSON errors
- •Trailing commas — Not allowed after the last item
- •Single quotes — JSON requires double quotes
- •Unquoted keys — Object keys must be quoted
- •Comments — Standard JSON does not support comments
