Feature flags, or feature toggles, have become essential in modern software development. These mechanisms allow developers to turn features on or off in a production environment without deploying new code. Feature flags offer a powerful way to test new features, perform A/B testing, roll out features gradually, and manage emergency switches. By decoupling feature deployment from code releases, feature flags empower teams to maintain continuous integration and continuous delivery (CI/CD) pipelines, leading to faster iterations and more controlled rollouts.
