What are the two main components of a feature flag?

Name, App Settings
Name, one or more filters
Feature manager, one or more filters
Environment, App Settings

The correct answer is: Name, one or more filters

The two main components of a feature flag are its name and one or more filters. The name serves as a unique identifier for the feature, allowing developers to easily reference and manage the flag within the codebase or configuration settings. Filters are crucial as they determine under what conditions the feature will be enabled or disabled for different users or environments. This can involve targeting specific user segments, geographical locations, or even certain application states, providing granular control over the feature's rollout. This capability helps in managing risk, allowing teams to test new features on a limited basis before a full deployment, thus enhancing stability and user experience. Understanding this concept is vital for implementing feature flags effectively in application development, as it facilitates controlled experimentation and iterative development processes.
