       * The Transition component lets you describe a transition from one component
       * state to another _over time_ with a simple declarative API. Most commonly
       * it's used to animate the mounting and unmounting of a component, but can also
       * be used to describe in-place transition states as well.
       *
       * ---
       *
       * **Note**: `Transition` is a platform-agnostic base component. If you're using
       * transitions in CSS, you'll probably want to use
       * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)
       * instead. It inherits all the features of `Transition`, but contains
       * additional features necessary to play nice with CSS transitions (hence the
       * name of the component).
       *
       * ---
       *
       * By default the `Transition` component does not alter the behavior of the
       * component it renders, it only tracks "enter" and "exit" states for the
       * components. It's up to you to give meaning and effect to those states. For
       * example we can add styles to a component when it enters or exits:
       *
       * ```jsx
       * import { Transition } from 'react-transition-group';
       *
       * const duration = 300;
       *
       * const defaultStyle = {
       *   transition: `opacity ${duration}ms ease-in-out`,
       *   opacity: 0,
       * }
       *
       * const transitionStyles = {
       *   entering: { opacity: 1 },
       *   entered:  { opacity: 1 },
       *   exiting:  { opacity: 0 },
       *   exited:  { opacity: 0 },
       * };
       *
       * const Fade = ({ in: inProp }) => (
       *   <Transition in={inProp} timeout={duration}>
       *     {state => (
       *       <div style={{
       *         ...defaultStyle,
       *         ...transitionStyles[state]
       *       }}>
       *         I'm a fade Transition!
       *       </div>
       *     )}
       *   </Transition>
       * );
       * ```
       *
       * There are 4 main states a Transition can be in:
       *  - `'entering'`
       *  - `'entered'`
       *  - `'exiting'`
       *  - `'exited'`
       *
       * Transition state is toggled via the `in` prop. When `true` the component
       * begins the "Enter" stage. During this stage, the component will shift from
       * its current transition state, to `'entering'` for the duration of the
       * transition and then to the `'entered'` stage once it's complete. Let's take
       * the following example (we'll use the
       * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):
       *
       * ```jsx
       * function App() {
       *   const [inProp, setInProp] = useState(false);
       *   return (
       *     <div>
       *       <Transition in={inProp} timeout={500}>
       *         {state => (
       *           // ...
       *         )}
       *       </Transition>
       *       <button onClick={() => setInProp(true)}>
       *         Click to Enter
       *       </button>
       *     </div>
       *   );
       * }
       * ```
       *
       * When the button is clicked the component will shift to the `'entering'` state
       * and stay there for 500ms (the value of `timeout`) before it finally switches
       * to `'entered'`.
       *
       * When `in` is `false` the same thing happens except the state moves from
       * `'exiting'` to `'exited'`.

       * and `exit` states of the transition. The first class is applied and then a
       * second `*-active` class in order to activate the CSS transition. After the
       * transition, matching `*-done` class names are applied to persist the
       * transition state.
       *
       * ```jsx
       * function App() {
       *   const [inProp, setInProp] = useState(false);

       *         </div>
       *       </CSSTransition>

       *   );
       * }
       * ```
       *
       * When the `in` prop is set to `true`, the child component will first receive
       * the class `example-enter`, then the `example-enter-active` will be added in
       * the next tick. `CSSTransition` [forces a
       * reflow](https://github.com/reactjs/react-transition-group/blob/5007303e729a74be66a21c3e2205e4916821524b/src/CSSTransition.js#L208-L215)
       * between before adding the `example-enter-active`. This is an important trick
       * because it allows us to transition between `example-enter` and
       * `example-enter-active` even though they were added immediately one after
       * another. Most notably, this is what makes it possible for us to animate
       * _appearance_.
       *
       * ```css
       * .my-node-enter {
       *   opacity: 0;
       * }
       * .my-node-enter-active {
       *   opacity: 1;
       *   transition: opacity 200ms;
       * }
       * .my-node-exit {
       *   opacity: 1;
       * }
       * .my-node-exit-active {
       *   opacity: 0;
       *   transition: opacity 200ms;
       * }
       * ```
       *
       * `*-active` classes represent which styles you want to animate **to**, so it's
       * important to add `transition` declaration only to them, otherwise transitions
       * might not behave as intended! This might not be obvious when the transitions
       * are symmetrical, i.e. when `*-enter-active` is the same as `*-exit`, like in
       * the example above (minus `transition`), but it becomes apparent in more
       * complex transitions.
       *
       * **Note**: If you're using the
       * [`appear`](http://reactcommunity.org/react-transition-group/transition#Transition-prop-appear)
       * prop, make sure to define styles for `.appear-*` classes as well.

        /**
         * The animation classNames applied to the component as it appears, enters,
         * exits or has finished the transition. A single name can be provided, which
         * will be suffixed for each stage, e.g. `classNames="fade"` applies:
         *
         * - `fade-appear`, `fade-appear-active`, `fade-appear-done`
         * - `fade-enter`, `fade-enter-active`, `fade-enter-done`
         * - `fade-exit`, `fade-exit-active`, `fade-exit-done`
         *
         * A few details to note about how these classes are applied:
         *
         * 1. They are _joined_ with the ones that are already defined on the child
         *    component, so if you want to add some base styles, you can use
         *    `className` without worrying that it will be overridden.
         *
         * 2. If the transition component mounts with `in={false}`, no classes are
         *    applied yet. You might be expecting `*-exit-done`, but if you think
         *    about it, a component cannot finish exiting if it hasn't entered yet.
         *
         * 2. `fade-appear-done` and `fade-enter-done` will _both_ be applied. This
         *    allows you to define different behavior for when appearing is done and
         *    when regular entering is done, using selectors like
         *    `.fade-enter-done:not(.fade-appear-done)`. For example, you could apply
         *    an epic entrance animation when element first appears in the DOM using
         *    [Animate.css](https://daneden.github.io/animate.css/). Otherwise you can
         *    simply use `fade-enter-done` for defining both cases.
         *
         * Each individual classNames can also be specified independently like:
         *
         * ```js
         * classNames={{
         *  appear: 'my-appear',
         *  appearActive: 'my-active-appear',
         *  appearDone: 'my-done-appear',
         *  enter: 'my-enter',
         *  enterActive: 'my-active-enter',
         *  enterDone: 'my-done-enter',
         *  exit: 'my-exit',
         *  exitActive: 'my-active-exit',
         *  exitDone: 'my-done-exit',
         * }}
         * ```
         *
         * If you want to set these classes using CSS Modules:
         *
         * ```js
         * import styles from './styles.css';
         * ```
         *
         * you might want to use camelCase in your CSS file, that way could simply
         * spread them instead of listing them one by one:
         *
         * ```js
         * classNames={{ ...styles }}
         * ```
         *
         * @type {string | {
         *  appear?: string,
         *  appearActive?: string,
         *  appearDone?: string,

         *  enterActive?: string,

         *  exit?: string,
