git checkout: Switches to a different branch or commit. This command is used to switch between different versions of the code.
git merge: Merges changes from one branch into another. This command is used to incorporate changes from a feature branch into the main development branch.
git pull: Pulls changes from the remote repository to the local repository. This command is used to keep the local repository up to date with the remote repository.
git push: Pushes local commits to the remote repository. This command is used to share changes made locally with other team members.
