/**
 * A transition component inspired by the excellent
 * [ng-animate](https://docs.angularjs.org/api/ngAnimate) library, you should
 * use it if you're using CSS transitions or animations. It's built upon the
 * [`Transition`](https://reactcommunity.org/react-transition-group/transition)
 * component, so it inherits all of its props.
 *
 * `CSSTransition` applies a pair of class names during the `appear`, `enter`,
 * 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);
 *   return (
 *     <div>
 *       <CSSTransition in={inProp} timeout={200} classNames="my-node">
 *         <div>
 *           {"I'll receive my-node-* classes"}
 *         </div>
 *       </CSSTransition>
 *       <button type="button" onClick={() => setInProp(true)}>
 *         Click to Enter
 *       </button>
 *     </div>
 *   );
 * }
 * ```
 *
 * 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 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'`.
