What does @@ mean?
It is the chunk header, showing the line numbers where the changes occurred in the original and new files.
Why merge conflicts?
When two people change the same lines in a file, Git cannot automatically decide which one to keep.
💡 Tips
- Use "Ignore Whitespace" if the only changes are indentation fixes.
