Git is a version control system that allows developers to track changes to their code over time. It is important because it allows developers to collaborate on projects, keep track of changes, and identify any issues that may arise.
For example, if a developer is working on a project and makes a change to their code, they can commit the change to Git. This will allow other developers to see the change and review it before it gets merged into the main codebase. If there are any issues, they can be identified and fixed before the code gets released.
