Git worktree lets developers work on multiple branches simultaneously without stashing

Git worktree is a built-in Git feature that allows developers to maintain multiple working directories linked to different branches, all sharing the same commit history. Unlike the common git stash workflow, each worktree folder operates independently with its own files, environment variables, and untracked content. This eliminates the need to stash and switch branches when handling urgent hotfixes or pull request reviews mid-feature. Developers can create a new worktree with a single command, list all active ones, and remove them cleanly once work is done. Best practices include keeping worktrees short-lived, using ticket IDs in branch names for traceability, and assigning different local ports to avoid service conflicts between environments.
