The core idea behind the Feature Branch Workflow is that all feature development should take place in a dedicated branch instead of the
master branch. This encapsulation makes it easy for multiple developers to work on a particular feature without disturbing the main codebase. It also means the
master branch will never contain broken code, which is a huge advantage for continuous integration environments.
Encapsulating feature development also makes it possible to leverage pull requests, which are a way to initiate discussions around a branch. They give other developers the opportunity to sign off on a feature before it gets integrated into the official project. Or, if you get stuck in the middle of a feature, you can open a pull request asking for suggestions from your colleagues. The point is, pull requests make it incredibly easy for your team to comment on each other’s work.
