A react component library for iTwinUI

import * as React from 'react';
/**
 * Wrapper over `useState` that always gives preference to the
 * controlled state (which often comes from a prop).
 *
 * This is helpful when a component needs to support both uncontrolled
 * and controlled states. If controlled value/setter is not passed,
 * then it will work just like a regular `useState`.
 *
 * @example
 * const [state, setState] = useControlledState(null, props.value, props.onChange);
