Meme transcription: Panel 1. Two images of JSON, one is the empty object, one is an object in which the key name maps to the value null. Caption: “Corporate needs you to find the difference between this picture and this picture”
Panel 2. The Java backend dev answers, “They’re the same picture.”
I don't get it. The key still gets declared, but it's value is null. "name" in an empty object would return undefined, not null, correct?
(Yes, this joke whooshed, but I am curious now.)
there is no "undefined" in java. this would either be a map containing the key value pair ("name", null) or it would be mapped to an object of some class with an attribute "name" which can hold a null value. in any case {} wont equal {"name":null}.
There's no "undefined" in JSON either
