Question

(d) object

I have been asked this question in semester exam.

Enquiry is from Parsing Values using JavaScript topic in section Parsing, Benchmarking and Logging of JavaScript

Answer 1

Right answer is (c) both text and reviver

To explain: The JSON.parse() method can optionally transform the result with a function. The parameters of the method JSON.parse() are :

text : The string to parse as JSON.

reviver : If a function, prescribes how the value originally produced by parsing is transformed, before being returned.
