JSON objects are written in curly brackets ({}).
JSON object syntax
Objects can contain multiple key/value (key/value) pairs.
key must be a string, value can be a legal JSON data type (string, number, object, array, Boolean or null).
Use colon (:) to separate key and value.
Each key/value pair is separated by commas (,).
