Using single quotes in JSON (valid in JavaScript but not in JSON)
JSON requires double quotes for all strings and keys. Use: {"key": "value"} not {'key': 'value'}
Including trailing commas after the last item in arrays or objects
JSON does not allow trailing commas. Remove the comma after the last element: [1, 2, 3] not [1, 2, 3,]
