Description: A feature toggle is a technique that allows developers to enable or disable software features without deploying new code. This practice has become essential in agile development and continuous delivery, as it provides a flexible way to manage the lifecycle of application features. Feature toggles allow development teams to implement new functionalities in a production environment while keeping them hidden from users until they are ready to be activated. This not only facilitates A/B testing and feedback collection but also minimizes the risks associated with launching new features. Additionally, toggles can be used to manage access to specific functionalities based on user profiles, allowing for more effective customization. In summary, feature toggles are a powerful tool that enhances software quality and user experience by allowing more granular control over the functionalities available in an application.
