Learn branch and tag references.
What Are Git Refs?
Refs are named references used to access Git objects. A branch reference usually points to the latest commit on that branch. Instead of memorizing long hash values, you can use meaningful names such as main or feature.
.git/refs/
├── heads/
└── tags/Refs allow Git to track specific points in commit history by name.
Heads and Tags References
refs/heads represents local branches, while refs/tags represents tags. A branch reference can move forward when a new commit is created. Tags are generally used to identify a specific commit, such as a release or an important point in history.
.git/refs/
├── heads/
│ └── main
└── tags/
└── v1.0These two reference types allow commit history to be named for different purposes.
