Version control helps developers track changes in their projects.
It allows teams to work together safely without losing code.
Why Version Control Is Important
Without version control:
- Changes can be lost
- Mistakes are hard to fix
- Teamwork becomes confusing
What Is Git
Git is the most popular version control system.
It records every change made to files over time.
Basic Version Control Concepts
Some common terms you should know:
- Repository: the project storage
- Commit: saving changes
- History: record of all changes
Each commit saves your progress safely.
Working with Teams
In team projects, version control helps:
- Combine work from different developers
- Avoid overwriting each other's changes
- Track who changed what
Using Online Repositories
Developers often store projects on platforms like:
- GitHub
- GitLab
- Bitbucket
These platforms allow sharing code and collaborating remotely.
Common Version Control Mistakes
- Not saving changes regularly
- Making unclear commit messages
- Editing production files directly
Why Version Control Matters for Jobs
Most companies use Git in daily work.
Knowing version control is required for frontend and backend roles.
Simple Commit Message Examples
Good commit messages are:
- Clear
- Short
- Descriptive
These messages explain exactly what changed.
