commit
Domain: Version Control
🎯 Motivation
A commit is a saved snapshot of your code at a specific point in time. Writing clear commit messages helps your future self and teammates understand why each change was made, which is a habit every developer should build early.
📋 Concrete Example
After fixing a bug you run git commit -m "fix: handle empty username in login form" to record the change with a descriptive message that explains the fix.
🔗 Analogy
A commit is like pressing “save” in a video game at a checkpoint. You can always reload that exact moment if something goes wrong later.
