What happens if delete() is called on something that isn't a map? like Json true or Json [1, 2, 3]? Can we add tests for this?

[MarkMcCulloh]

It should return true (matching the return comment).
null is also technically valid json and that would throw here (bad), but most of our json methods wouldn't correctly handle null anyways.
Agree a test would be good, my b for approving without more tests.

[partha04patel]

I could try adding extra tests for some of those edge cases in another PR!
