What is GitHub?
GitHub is a platform used by developers to store, manage, and collaborate on code.
It is built on top of Git, a version control system that tracks changes to files over time.
With GitHub, developers can:
- Save their code online
- Track every change made to their code
- Collaborate with other developers
- Review and approve changes
- Manage software projects
In simple terms:
GitHub = cloud platform for managing code and collaboration.
Why Do People Use GitHub?
Developers use GitHub for several key reasons.
1. Version Control
GitHub tracks every change in a project.
This means you can:
- see who changed what
- restore older versions
- experiment without breaking the main code
This prevents accidental loss of work.
2. Collaboration
Multiple developers can work on the same project simultaneously.
GitHub helps teams:
- coordinate work
- review code changes
- discuss improvements
- merge contributions safely
3. Code Backup
Because projects are stored online, GitHub acts as a secure backup of code.
If a developer loses their computer, the project is still safe.
4. Open Source Development
GitHub is the largest open-source ecosystem.
Millions of developers publish projects publicly so others can:
- learn from the code
- contribute improvements
- reuse components
5. Project Management
GitHub includes tools to manage development work:
- Issues
- Pull Requests
- Project boards
- Milestones
- Code reviews
These tools help organize large software projects.
