Git Worktree Lets You Work on Multiple Branches Without Stashing

Git's worktree feature allows developers to check out multiple branches simultaneously in separate directories, eliminating the need for repetitive git stash operations. Running 'git worktree add' creates a linked working tree that shares the same repository and object store, rather than creating a full clone. Each linked worktree maintains its own HEAD and index, but all branches, stashes, and refs remain shared across every worktree. A safety mechanism prevents the same branch from being checked out in more than one worktree at a time. Worktrees can be cleanly removed with 'git worktree remove', and orphaned records from manually deleted folders can be cleaned up using 'git worktree prune'.
