In this Git for Beginners lesson, you will learn how to view Git commit history, check file changes, undo uncommitted changes, and fix the last commit.
In this lesson, you will learn how to read Git history, check changes with git diff, undo uncommitted changes with git restore, and fix the last commit using git commit --amend.
I also explain why small, clear commits and good commit messages make your Git history easier to understand.
