How Does Feature Flags - Frontend vs Backend Work?

Feature flags let you turn parts of a website on or off without changing the whole thing, like having a light switch that lets you choose which room gets light.

Imagine you're playing with building blocks. On the frontend, that's like what you see and touch, the colorful blocks stacked up. On the backend, that's like the hidden glue holding everything together, the strings and clips you can't see but need to keep the tower from falling.

On the frontend, feature flags are like a secret switch in your toy box. When you press it, a new block appears, or maybe a robot starts moving! You don’t need to take everything apart, just flip that switch, and voilà!

On the backend, feature flags work like a hidden message between your toys and the robot inside the box. If the message says "go," the robot moves; if it says "stop," it stays still. This lets grown-ups make changes without you even noticing.

Both kinds of feature flags help people add or fix things quickly, just like having extra blocks or new instructions for your toy robot!
