👉 Commits are a type of code change that occurs when a developer makes changes to the source code of an existing software application. Commits are typically made by a developer who has modified or added functionality to an existing application, and they can be tracked using various tools such as GitHub, GitLab, or Bitbucket. Commits are important for tracking the development history of a project, allowing other developers to understand how changes were made and what was changed in the source code.
