Comparing differences between specific commits helps analyze code evolution, debug issues, and understand what changed between any two points in project history. As the creator of CoreUI with extensive Git experience across numerous projects, I frequently compare commits to track down bugs or understand feature implementations. The most precise method is using git diff commit1 commit2 with specific commit hashes or references. This approach provides exact comparison between any two commits regardless of branch or timeline.

Comparing differences between Git branches is essential for code reviews, understanding feature changes, and planning merges in collaborative development. As the creator of CoreUI with over 25 years of development experience, I regularly compare branches to review feature implementations and assess merge impacts. The most straightforward approach is using git diff branch1 branch2 to see all differences between two branches. This command provides comprehensive insight into what changes will be introduced when merging branches.
