Why developers need Git
Git is a version control system: it saves a history of code changes, lets you roll back to an earlier version, and allows multiple developers to work on the same project without conflicts.
Almost no team-based development work happens without Git — it's one of the few tools checked even in junior interviews, regardless of specialization.
Basic commands to get started
| Command | What it does |
|---|---|
| git init | Creates a new Git repository in the current folder |
| git add . | Stages changed files, preparing them for a commit |
| git commit -m "message" | Saves the changes with a description |
| git status | Shows the current state of the repository |
| git push | Sends changes to a remote server (like GitHub) |
| git pull | Fetches the latest changes from a remote server |
| git branch | Lists or creates branches |
| git checkout -b name | Creates and switches to a new branch |
How to practice
- Create a GitHub account and set up your first repository for practice projects.
- Commit after every logical chunk of work, not everything at once at the end.
- Practice creating and switching between branches on a small project.
- Learn how to resolve simple merge conflicts — they come up regularly in real work.
Frequently Asked Questions
Do I need to know Git for a junior position?
Yes, basic Git commands are practically a required minimum for any developer position, including junior.
How long does it take to learn basic Git?
The core commands can be learned in a few days of practice — more advanced scenarios (rebasing, conflicts) come with experience.
