Checkout

ELI5 — The Vibe Check

Checkout is like teleporting to a different branch or going back in time to an old version. When you checkout a branch, all your files change to match that branch. It's how you switch between different workspaces.

Real Talk

Checkout switches your working directory to a different branch or commit. In modern Git, git switch is preferred for branch switching and git restore for file restoration, though checkout still works for both.

git checkout main
git checkout -b new-feature
# Modern alternatives:
git switch main
git switch -c new-feature

When You'll Hear This

"Checkout the main branch first." / "I need to checkout that old commit to see what happened."
