Git Diff
Git Diff is a command-line tool in Git that compares and displays differences between various Git objects, such as commits, branches, files, or the working directory and staging area. It highlights changes in content, including additions, deletions, and modifications, using a unified diff format to show line-by-line differences. This tool is essential for reviewing code changes, understanding commit history, and identifying conflicts during development.
Developers should use Git Diff to inspect changes before committing, review pull requests, debug issues by comparing versions, and resolve merge conflicts by analyzing differences between branches. It is particularly useful in collaborative workflows to ensure code quality, track modifications over time, and maintain a clean version history, making it a fundamental skill for any developer working with Git.
