About Diff Checking
A diff checker compares two versions of text or code to identify what has changed between them. This is essential for code review, document comparison, and tracking changes over time.
Common Uses:
- Code Review: Compare different versions of source code files
- Document Comparison: Track changes in text documents, contracts, or articles
- Configuration Files: Identify differences in config files across environments
- Debugging: Compare expected vs actual output to find issues
- Merge Conflicts: Understand differences before merging changes
