Result / expected behavior

{
  "equal": false,
  "changes": [
    {
      "path": "/count",
      "kind": "changed",
      "before": 1,
      "after": 2
    }
  ]
}

Available options: Updated JSON / JSON5

Scope and limitations

Uses JavaScript number semantics, so very large integers may lose precision. Arrays are compared by index, not object identity.

Common mistakes

The second document must not be empty. Use text diff for whitespace or original numeric spelling differences.
