What is Version Control?

Version Control is an important aspect of software development and collaborative projects. It refers to the systematic management of changes made to a project’s codebase, documents, or any set of files over time. The primary objectives of version control are to:

1. Track Changes: Version control allows you to monitor changes made to files, providing a detailed history of who made the changes, when, and what specific modifications were implemented.
2. Collaborate Effectively: In collaborative environments, multiple individuals may be working on the same project simultaneously. Version control enables seamless collaboration by managing and merging changes made by different team members, preventing conflicts and ensuring a cohesive final project.
3. Restore Previous State: Developers can revert to previous version of the project, enabling them to roll back to stable state in case of errors, bugs or need to review project at a specific point in time.
4. Branching and Merging: Version control systems, such as GitLab, facilitate the creation of branches for parallel development efforts. These branches can be merged back into the main codebase, allowing for the integration of distinct features or fixes.
5. Facilitate Code Reviews: Version control systems often include tools for code reviews, where team members can collaboratively assess and discuss proposed changes before they are merged into the main project.

Examples of VCS:

• Mercurial
