What are Feature Flags?

Feature flags, also known as feature toggles or feature switches, are a technique used in software development to enable or disable certain functionality in a program at runtime. This allows developers to easily turn on or off new features, or to perform A/B testing, without having to deploy new code. Feature flags are typically implemented as a system of flags or switches that are stored in a configuration file or database, and can be easily manipulated by developers or administrators. This allows them to quickly and easily make changes to the functionality of a program without having to go through the entire development, testing, and deployment process.
