/**
|
|
* A custom hook for managing both controlled and uncontrolled component states.
|
|
*
|
|
* This hook allows a component to support both controlled and uncontrolled
|
|
* states by determining whether the `controlledValue` is provided. If it is
|
|
* undefined, the hook falls back to using the internal state.
|
|
*
|
|
* @example
|
|
* // Uncontrolled usage
|
|
* const [value, setValue] = useControlledValue(0, undefined);
|
|
*
|
|
* // Controlled usage
|
|
* const [value, setValue] = useControlledValue(0, props.value);
|
|
*
|
|
* @template T - The type of the value.
|
|
* @param defaultValue The initial value for the uncontrolled state.
|
|
* @param controlledValue The value for the controlled state. If undefined, the
|
|
* component will use the uncontrolled state.
|
|
* @returns A tuple where the first element is the current value (either
|
|
* controlled or uncontrolled) and the second element is a setter function to
|
|
* update the value.
