Merge is used to combine code from one branch into another.
Merging creates a new combined commit, losing the history of the source branch.

02:32 🚀 Git Rebase Introduction

Rebase also merges branches but maintains the history of source commits.
It creates new commits with different hash codes for the source branch’s commits.

05:31 📊 Practical Comparison: Merge

After a merge, the source branch’s commits are combined into a new commit in the target branch.
The source branch’s individual commit history is lost in the target branch.

07:48 💡 Practical Comparison: Rebase

After a rebase, the source branch’s commits are merged into the target branch with new commit hash codes.

22 GIT Stash StashPop Merge Conflict

00:00 📚 Understanding Git Stash and Merge Conflicts

Git Stash is used to save work in progress changes before merging or pulling from the remote repository.
Merging code from different developers can lead to conflicts that need to be resolved through communication and manual intervention.

07:52 🤖 Taking a Stash and Handling Merge Conflicts

When trying to pull changes from the remote repository, Git may require you to stash or remove uncommitted changes to proceed.
Stashing your work in progress changes allows you to pull the latest changes and then pop them back when needed.
Merge conflicts occur when code changes from different developers overlap, and they must be resolved manually through communication and selective code acceptance.

14:40 🤝 Resolving Merge Conflicts and Using Stash Effectively

Resolving merge conflicts requires communication and agreement between developers on which code changes to accept.
Git Stash is a useful tool for temporarily saving and later retrieving work in progress changes when dealing with merge conflicts.

It doesn’t remove the entire file but only the changes made in that commit.
The revert operation generates a new commit with a clear reason and a new commit ID.

04:20 🛠️ Resolving Revert Conflicts

When reverting multiple commits, conflicts can occur due to commit history and changes being reverted.
You need to resolve these conflicts by choosing which changes to keep and which to remove.
Git Revert helps maintain commit history even during the conflict resolution process.
