Have you ever played a challenge and thought that one or more solutions contain exactly the same changes? Well, let us explain why this might not be the case.

Certain solutions may call the same method in one file, but the definition of that method might be updated in a different file.

The files that contain updates for the selected solution are always in bold orange and marked with a red 'X '

For example, in Solution 1, the vulnerability is only marked in routes.js, while some other files contain changes. If one of the other solutions has the same changes for routes.js, the changes in the other files might be different.

Hot Tip: If you want to compare two specific solutions, use the drop-down list on the left-hand side.

This will cause the file tree and file view to mark the differences between Solution 3 and Solution 1 instead of comparing it to the vulnerable code.

If this method shows no differences between two solutions, please report this issue to our support team using the "Provide Feedback" button
