To create a new branch in Git, you can use the git checkout command followed by the flag -b and then type the name of the branch you need to make.
For example, to make a branch called my-new-branch you can use the git checkout command like this,
# Creates a new git branch
git checkout -b my-new-branch
This will create a branch called my-new-branch and will automatically check you into it (aka, set the current working branch to my-new-branch).
That's all 😃!
