A branch allows you to temporarily isolate some work from the rest. At any point, if you want to integrate the changes from a branch with the changes on the other fork, you can merge these changes back. Branches are often used for working on not-yet-complete features, proofs of concept, or hotfixes. Using branches allows you to later decide which changes to include in the next version and which not to.
