Arrays are compared element by element by index. Elements at the same index are compared, new elements beyond the original array length are marked as added, and missing elements are marked as removed.
Yes, if array elements are reordered, the tool will show modifications at each index where the value changed. For example, if [1,2,3] becomes [3,2,1], it will show modifications at indices 0 and 2.
Yes! Arrays containing objects are fully supported. Each object in the array is compared deeply, so you can see changes to nested properties within array elements.
The tool compares elements up to the length of the shorter array, then marks all remaining elements in the longer array as added (if in the right array) or removed (if in the left array).
Compare shopping cart arrays before and after updates to see which items were added, removed, or had their quantities/prices modified.
Compare arrays representing ordered lists (like leaderboards or rankings) to see how positions changed and which items moved.
Track changes to arrays of data records, such as user lists, product catalogs, or event logs, to see what was added or removed.
Array order matters - [1,2,3] is different from [3,2,1]. If order doesn't matter for your use case, consider sorting arrays before comparison.
For arrays of objects, changes to object properties will show as modifications at that array index.
Empty arrays [] are different from arrays with null elements [null]. Be aware of this distinction.
If you're comparing arrays where elements can be identified by a unique key (like 'id'), consider using a custom comparison that matches by key rather than index.
