JS has two built-in Json methods
1. JSON.parse()--Convert string to object
JSON.parse() is used to convert a JSON string into a JavaScript object.

JSON.parse(text[, reviver])
Parameter description:
text:Required, a valid JSON string.
reviver: Optional, a function that converts the result. This function will be called for each member of the object.
Return value: Returns the converted object of the given JSON string.
