What is the purpose of the JSON.parse() method in JavaScript?

Question

BlackTom AI · Accepted Answer

When evaluating the purpose of JSON.parse() in JavaScript, it helps to examine what each option implies about JSON handling.
Option 1: 'To convert a JavaScript object into a JSON string' — This describes JSON.stringify(), not JSON.parse(). Therefore this statement is incorrect because parse is the inverse operation of stringify.
Option 2: 'To parse a JSON string and convert it into a JavaScript object' — This is the accurate description. JSON.parse() reads a string in JSON format and constructs the corresponding JavaScript value or object, enabling code to work with structured data.
Option 3: 'To format a date in JSON format' — JSON.parse() does not perform date formatting. It parses data from a JSON string; it does not transform or format dates by itself. Any date handling would be done after parsing, often by converting strings to Date objects.
Option 4: 'To remove a property from a JavaScript object' — This is a general object manipulation operation (e.g., delete obj.prop) and is unrelated to parsing JSON strings. JSON.parse() does not delete properties.
In summary, only option 2 correctly describes the function of JSON.parse(), while the other options misidentify the method’s purpose or describe unrelated operations.
