What is a git worktree: how it works internally and when to use it
A git worktree is an additional working directory for the same repository: a second folder with its own files, its own active branch, and its own staging, which shares the history, branches, and configuration with the original folder. With it, you can have main open in one folder and feature/login in another at the same time, without cloning the repository twice and without having to stash every time…
A git worktree is an additional working directory of the same repository, allowing multiple branches to be worked on simultaneously. It was introduced in git 2.5 in 2015 and enables users to have multiple active branches, such as main and feature/login, in separate folders. A git worktree has its own HEAD, index, and files but shares commits, branches, configuration, and hooks with the main worktree. It does not duplicate the repository's history, making it a quick and efficient solution.
