What is JSON?

Accepted Answer

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is commonly used in web APIs and configuration files.

Question 2

What makes JSON invalid?

Accepted Answer

Common JSON errors include: trailing commas after the last item, single quotes instead of double quotes, unquoted keys, missing commas between items, and comments (JSON does not support comments).

Question 3

What is the difference between minified and formatted JSON?
