Does property order matter?

No. Objects are compared by key regardless of order. Two objects with the same keys and values in different order are considered identical.

How are arrays compared?

Arrays are compared by index. If one array is longer, extra elements are shown as added or removed.

What does the path mean?

The path (e.g., $.config.theme) shows where in the JSON structure the difference occurs, using dot notation for objects and brackets for arrays.

Does it validate JSON first?

Yes. Both inputs are validated before comparison. If either side has invalid JSON, you'll see a specific error message.
