When to use Stringify and when to use parse.

[Shubham15]

Hii,

I have been developing ServiceNow projects and was using JSON.parse and stringify. But I am not exactly sure when to use them and what is the difference between them. 

Can anyone please brief me about it.

Hii Shubham,

They are the complete opposite of each other.

JSON.parse() is used for parsing data that was received as JSON; it deserializes a JSON string into a JavaScript object.

JSON.stringify() on the other hand is used to create a JSON string out of an object or array; it serializes a JavaScript object into a JSON string.

JSON.stringify(obj) - Takes any serializable object and returns the JSON representation as a string.

JSON.stringify() -> Object To String.

JSON.parse(string) - Takes a well formed JSON string and returns the corresponding JavaScript object.

JSON.parse() -> String To Object.

Hello,

stringify() takes a JavaScript object and then transforms it into a JSON string. JSON. parse() takes a JSON string and then transforms it into a JavaScript object.
