JSON Tips

JSON requires double quotes for strings and property names. Single quotes are not valid.

Unlike JavaScript, JSON does not allow trailing commas after the last item in arrays or objects.

All property keys in JSON must be wrapped in double quotes, even simple names.

JSON supports: strings, numbers, booleans, null, arrays, and objects. No functions or undefined.
