Explanation:
JSON data is written as name/value pairs.
A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value:
“name”:”Mark”
JSON can use arrays. Array values must be of type string, number, object, array, boolean or null. For example:
{
“name”:”John”,
“age”:30,
“cars”:[ “Ford”, “BMW”, “Fiat” ]
}
JSON can have empty object like “taskId”:{}
