Description: The ‘Add branch’ command in Git is used to create a new branch in the repository. Branches are a fundamental feature of Git that allows developers to work on different versions of a project simultaneously. By creating a new branch, an isolated environment is established where changes can be made without affecting the main branch, typically called ‘main’ or ‘master’. This is especially useful in software development, as it allows for experimentation with new features, bug fixes, or testing without compromising the stability of the existing code. The command is executed with the syntax ‘git branch branch_name’, where ‘branch_name’ is the identifier assigned to the new branch. Additionally, branches in Git are lightweight and quick to create, promoting an agile and collaborative workflow among team members. The ability to merge branches also allows for controlled integration of changes, which is essential for maintaining code quality in complex projects.
