Git worktrees is a feature that allows developers to maintain multiple working directories within a single Git repository, enabling simultaneous work on different branches or versions without the need for separate clones. This feature enhances workflow flexibility by letting users create isolated workspaces, each with its own set of files and branches, while sharing the same underlying repository data. Worktrees facilitate concurrent development, testing, or bug fixing by providing a lightweight and efficient solution for managing multiple contexts within a single repository.

Example use-case

Consider a software developer working on a feature branch in a Git repository who suddenly needs to address a critical bug on the main branch. Instead of stashing changes, switching branches, and potentially losing context, the developer can use Git worktrees. They create a new worktree associated with the main branch, allowing them to simultaneously work on the bug fix in a separate directory. This way, the developer maintains a clear separation between the feature development and the urgent bug fix without the need for multiple clones or constant branch switching.
