questions
How are arrays compared?
By default, arrays are compared by position (index 0 vs index 0, etc.). Enable "Ignore Array Order" to sort arrays before comparing, which treats [1,2,3] and [3,1,2] as identical.
What is JSONPath notation?
JSONPath uses dot notation to describe the location of a value. For example, $.user.name means the "name" field inside the "user" object at the root level.
Can I compare deeply nested objects?
Yes. The diff algorithm recursively walks both JSON trees and detects changes at any depth. Each change includes the full path from root to the changed field.
