Version Control Systems

Managing Code Changes and Collaboration

Understanding Version Control

Git is a distributed version control system that tracks changes in fil

on the same project simultaneously, maintains a complete history of changes, and enables branching and merging.

Git is the most popular version control system, used by 95%+ of developers.

A merge conflict occurs when Git cannot automatically merge changes be

branches. You must manually resolve conflicts by choosing which changes to keep. Use merge tools or edit files

directly to resolve conflicts, then commit the resolution.

Frequently asked questions

What is a development branch and how does it relate to feature branches and release branches?

develop is integration branch, features branch from develop, releases prepare for production, hotfixes fix production

Why are issues useful for managing release cycles?

Issues. It’s complex but good for release cycles.

How can I undo a commit in Git?

You can use the `git reset` command to undo commits, with options that either preserve changes or discard them entirely. Alternatively, you can create a new commit that reverses the effects of the original commit using `git revert`.

What are the differences between `git reset` and `git revert`?

`git reset` allows you to undo commits by moving the branch pointer, potentially keeping changes in your working directory. Conversely, `git revert` creates a new commit that negates the effects of a previous commit without altering the history.
