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.”
That’s what undefined is for
Undefined is not part of JSON specification. It’s also not a thing in Java.
Yeah my bad, it would still require the java dev to leave the keys out
To be fair, just because
obj.foois undefined, that doesn’t mean the key is missing. It could also be assigned the value undefined.const obj = { foo: undefined }vsconst obj = {}
