About JSON

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 based on a subset of JavaScript syntax.

Valid JSON Types:

• String: "text" (must use double quotes)
• Number: 42, 3.14159
• Object: {"key": "value"}
• Array: [1, 2, 3]
• Boolean: true or false
• null

Common JSON Errors:

• Using single quotes instead of double quotes for strings
• Missing commas between array items or object properties
• Trailing commas (not allowed in JSON)
• Unquoted property names (keys must be in double quotes)
• Including comments (not allowed in JSON)
