よくある質問

How is this different from a text diff?

A text diff cares about key order and whitespace. This walks the JSON structurally: {a:1,b:2} and {b:2,a:1} show zero differences.

What paths are used?

JSONPath-style: $.key, $.items[3].name. Copy them to jq or a JavaScript lookup.

Are arrays diffed by index or content?

By index - items are compared position-by-position. For unordered-set diffing, sort both arrays first.
