What are feature flags and how do they impact development?

Feature flags are tools that allow developers to enable or disable features in a software application without deploying new code. They can significantly impact development by allowing for safer testing, gradual rollouts, and easier rollback of features.

Can you explain how they help in testing new features?

Certainly! Feature flags enable developers to test new features in production with a subset of users. This way, they can gather feedback and monitor performance before a full rollout, reducing the risk of introducing bugs to all users.

Are there any downsides to using feature flags?

Yes, while feature flags offer many benefits, they can also lead to complexity in code management. If not managed properly, they can create technical debt and make the codebase harder to understand.

How can teams effectively manage feature flags?

Teams can manage feature flags by establishing clear guidelines for their use, regularly reviewing and cleaning up unused flags, and using tools that provide visibility into the status of each flag.
