Git is a widely-used version control system that allows developers to keep track of changes to their code over time. It allows multiple developers to work on the same codebase simultaneously, without the risk of overwriting each other’s changes.
When you create a new project using Git, it creates a local repository on your computer. This repository contains all of the files and directories in your project, along with a history of all of the changes that have been made to them.
You can make changes to your code and then use Git to “commit” them to the local repository. A commit is like a snapshot of your code at a specific point in time. Each commit has a unique identifier (known as a “SHA”) and contains a message describing the changes that were made.
You can also use Git to “push” your changes to a remote repository, such as one hosted on GitHub or GitLab. This allows other developers to access the latest version of your code, and also serves as a backup in case something goes wrong with your local repository.
One of the most powerful features of Git is branching. A branch is a separate version of your code that you can work on without affecting the main version of the code (also known as the “master” branch). You can create a new branch, make changes to it and then “merge” those changes back into the master branch when you’re ready. This allows for the development of new features in parallel and isolate them from the main codebase.
Git also allows you to collaborate with other developers by “pulling” changes from a remote repository and “merging” them with your local code. This can also be done by creating a “pull request” on platforms like GitHub, where other developers can review and merge the changes.
In conclusion, Git is a powerful version control system that allows developers to keep track of changes to their code over time. It allows multiple developers to work on the same codebase simultaneously, without the risk of overwriting each other’s changes. Git provides a feature like branching, pull and merge that makes collaboration and development much more efficient and streamlined. With Git, developers can work together on a project, collaborate with others, and easily revert to previous versions of their code.
