Frequently asked questions
- Does it compare word by word or line by line?
- The diff works at the line level, which is ideal for documents, configuration files, and notes where each line is a meaningful unit.
- Can I use it for code?
- Yes. It is handy for quick comparisons, though a dedicated version-control diff is better for large code reviews.
