Lecture 113:- Git Understanding Branches

In Git, a branch is a separate line of development that represents a specific set of changes to the code. When you create a new branch, it starts as a copy of the current branch (usually the main branch, called master), and you can make changes to the code in the new branch without affecting the main branch.

Branches are useful for several reasons:

1. Collaboration: If multiple people are working on the same codebase, they can each work on their own branches and merge their changes together when they're ready.
2. Experimentation: You can create a new branch to experiment with a new feature or idea, without affecting the stability of the main branch.
3. Bugfixes: If a bug is discovered in the code, you can create a new branch to fix the bug without affecting the rest of the codebase.

When you're working in Git, you're always on a specific branch. You can use the command git branch to see a list of all the branches in your repository, and the command git checkout to switch to a different branch.

When you make changes to the code in a branch, you can commit those changes to the branch using the git commit command. When you're ready to merge the changes from one branch into another (usually merging a feature branch into the main branch), you can use the git merge command.

It's important to use branches effectively in Git, to ensure that changes are properly isolated and reviewed before they're merged into the main codebase.
