Compare two JSON documents and get every change with its pointer, classified as
Compare two JSON documents and get every change with its pointer, classified as added, removed, retyped or revalued. Object key order is not a change. Array order is, unless you say the arrays are unordered. Numbers compare exactly, so 42.50 and 42.5 are the same value and two adjacent large integers are not.
