Parallel development Multiple developers can: - work on different tasks at the same time; - avoid interfering with each other; - avoid breaking the main branch (`main` / `master`). ### 2. Safe experiments - new ideas and features are built in separate branches; - failed changes can simply be deleted; - the main version of the project stays stable. ### 3. Convenient change management - each task = a separate branch; - easier code review and testing; - easier to track **which feature changed what**. ### 4. Release control - you can have `release`, `hotfix` branches; - fix bugs in production quickly; - prepare the next release in parallel. ## Important point Branches in Git: - are **lightweight and fast**; - do not copy files; - are **pointers to commits**. ## Short answer for an interview > **Branches allow parallel development, isolate changes, and let you safely merge them into the main code.**For the reviewerNote to the moderator (optional)Visible only to the moderator.
