JSON
Precision, structure, comparison and strict JSON parsing.
-
The JSON number is valid. Is the value still exact?
Syntax validity does not guarantee numeric precision. Follow a large identifier through parsing, formatting and comparison without losing a digit.
-
An inserted array item can look like three changes
An index-based diff answers what changed at each position. It does not infer item identity, moves or unordered collection semantics.
