Parsing JSON performance

Question

I have json with some objects in it. And only one object from json i need. So which approach will be better for speed and performance - parse only this object or parse whole document instead?

Answer 1

If you want to show only the particular JSON Object which may be either inside a JSON Object or JSON array itself then you just parse that particular JSON Object instead of parsing whole document.

Answer 2

If you are not going to use rest of the data, you can just parse the item you only need.

Answer 3

In theory, just the object would get you a result faster with lesser work times. So just parse the object you need.
