/**
 * A transition component inspired by the [vue transition modes](https://vuejs.org/v2/guide/transitions.html#Transition-Modes).
 * You can use it when you want to control the render between state transitions.
 * Based on the selected mode and the child's key which is the `Transition` or `CSSTransition` component, the `SwitchTransition` makes a consistent transition between them.
 *
 * If the `out-in` mode is selected, the `SwitchTransition` waits until the old child leaves and then inserts a new child.
 * If the `in-out` mode is selected, the `SwitchTransition` inserts a new child first, waits for the new child to enter and then removes the old child.
 *
 * **Note**: If you want the animation to happen simultaneously
 * (that is, to have the old child removed and a new child inserted **at the same time**),
 * you should use
 * [`TransitionGroup`](https://reactcommunity.org/react-transition-group/transition-group)
 * instead.
 *
 * ```jsx
 * function App() {
 *  const [state, setState] = useState(false);
 *  return (
 *    <SwitchTransition>
 *      <CSSTransition
 *        key={state ? "Goodbye, world!" : "Hello, world!"}
 *        addEndListener={(node, done) => node.addEventListener("transitionend", done, false)}
 *        classNames='fade'
 *      >
 *        <button onClick={() => setState(state => !state)}>
 *          {state ? "Goodbye, world!" : "Hello, world!"}
 *        </button>
 *      </CSSTransition>
 *    </SwitchTransition>
 *  );
 * }
 * ```
 *
 * ```css
 * .fade-enter{
 *    opacity: 0;
 * }
 * .fade-exit{
 *    opacity: 1;
 * }
 * .fade-enter-active{
 *    opacity: 1;
 * }
 * .fade-exit-active{
 *    opacity: 0;
 * }
 * .fade-enter-active,
 * .fade-exit-active{
 *    transition: opacity 500ms;
