- 2Each difference is listed with its path: + added, − removed, ~ changed.
Frequently asked questions
Does key order matter?
No. Objects are compared by key, so {"a":1,"b":2} and {"b":2,"a":1} are identical.
Does array order matter?
Yes. Arrays are compared position by position, because order is meaningful in JSON arrays.
Are 1 and 1.0 the same?
Yes. JSON numbers are compared by value, so 1 and 1.0 are equal, but 1 and "1" are different types.
