Feature Flag
Definition
A switch that lets teams turn a feature on or off without redeploying code.
In Plain English
A feature flag is like a light switch for a specific product capability.
Real-World Example
A beta feature can be enabled for five customers before everyone gets it.
Why It Matters for Your Work
Feature flags reduce launch risk and support gradual rollouts.
Common Mistake
Leaving old feature flags in the code forever, which creates complexity.
