What Is a Branch?
A Git branch allows you to keep track of different changes separately.
For example, let's say you have a big web project and you want to experiment with changing the color scheme. Instead of changing the entire project directly (as of right now, our master branch), you can create a new branch called color_scheme and work on that branch. When you're done, if you like the changes, you can merge the color_scheme branch back into the master branch to keep the changes. If you don't like the changes, you can simply delete the color_scheme branch and go back to the master branch.
Under the Hood
A branch is just a named pointer to a specific commit. When you create a branch, you are creating a new pointer to a specific commit. The commit that the branch points to is called the tip of the branch.
Because a branch is just a pointer to a commit, they're lightweight and "cheap" resource-wise to create. When you create 10 branches, you're not creating 10 copies of your project on your hard drive.
Assignment
Check which branch you're currently on by running:
Make sure you are in the webflyx directory before running the command.
git branch
Run and submit the CLI tests.
Tip
Remember, you should be on master because we set init.defaultBranch to master at the start of the course.
