- Q1. What is git stash ? and scenario when conflicts occurs
- Ans.
Git stash is a command in Git that temporarily shelves changes so you can work on something else.
Git stash is used to save changes that are not ready to be committed yet.
It allows you to switch branches without committing changes.
Conflicts can occur when stashed changes conflict with changes in the current branch.
You can resolve conflicts by applying the stash, resolving conflicts, and then committing the changes.
