Do array order differences count?

By default arrays are compared by index, so reordering shows as changes. Sort first if you only care about multiset equality.

Can deeply nested JSON be compared?

Yes. Nested objects and arrays diff with expandable paths. Very large payloads may slow rendering in the browser.

What if JSON syntax is invalid?

Both sides must parse as JSON. Invalid input shows an error location—you need valid syntax before diffing.
