# Theory
The `Switch` component in React Native is used to toggle between two states - typically representing an "on/off" or "true/false" selection. It provides users with a visual indicator of the current state and allows them to change it with a simple tap.

## Why Do We Need It?
1. **Binary Selection**:
   - Useful for scenarios where you need users to make a binary choice;
   - Commonly used for settings, preferences, or toggling certain features.
2. **User-Friendly**:
   - Provides a simple and intuitive interface for toggling between states;
   - Offers a visual cue of the current state, enhancing user experience.

## How to Work with Switch
- The `Switch` component is controlled through its `value` prop, which determines whether it is in the "on" or "off" state;
- We can use the `onValueChange` prop to specify a callback function that will be called when the user toggles the switch.
