What tool is commonly used for version control in Shopify theme development?

Git is commonly used for version control in Shopify theme development due to its powerful features that help developers manage their codebase effectively. Version control is essential in development as it allows multiple developers to work collaboratively on a project, track changes to the source code, and revert to previous versions if needed.

With Git, developers can maintain a history of their work, create branches for new features or experiments without affecting the main codebase, and merge changes back into the main project seamlessly. This not only streamlines the development process but also helps in managing updates and troubleshooting issues that may arise during theme development.

In contrast, while FileZilla is primarily an FTP client used to transfer files between a local computer and a server, it does not provide version control capabilities. The Shopify CLI is a command-line tool that aids in theme development, but it does not offer version control features. Dreamweaver is a web development tool that allows for code editing and design but is not specifically focused on version control like Git. Therefore, Git is the most suitable and widely adopted tool for this purpose in Shopify theme development.
