Again, since Git is a distributed version control system, multiple people can work on the same repository, but that can't be done without order, so, to do that each branch has the ability to create branches, where there's a default branch that has the original code, and each new branch is a clone of the default branch at the checkout time, to accept changes from a checked out branch, the repository's owner have to merge those changes with the default branch.
Branches in Git:
- Incredibly lightweight
- References to a specific commit -- nothing more
- A branch is a pointer that moves forward with every new commit
- The default branch name in git is master
- GitHub calls the default branch main
To create a new branch from the latest revision (last commit) of the default branch, run this command
git branch <branch-name>To switch to the new branch, run this command
git checkout <branch-name>You can also create a new branch and checkout into it at the same time using this command
git checkout -b <branch-name>To delete a branch that have been merged with the default branch or the branch that it has been checked out from, run this command
git branch -d <branch-name>To delete a branch without checking that it was merged into its default branch or the branch that it has been checked out from, run this command
git branch -D <branch-name>Keep in mind that this is a dangerous command, where it will delete the branch locally without any confirmation.
To delete a remote branch, run this command
git push <remote_name> --delete <branch_name>
