+
+> **ATTENTION!** To address many issues that have come up over the years, the API in v2 and above is not backwards compatible with the original [`React addon (v1-stable)`](https://github.com/reactjs/react-transition-group/tree/v1-stable).
+>
+> **For a drop-in replacement for `react-addons-transition-group` and `react-addons-css-transition-group`, use the v1 release. Documentation and code for that release are available on the [`v1-stable`](https://github.com/reactjs/react-transition-group/tree/v1-stable) branch.**
+>
+> We are no longer updating the v1 codebase, please upgrade to the latest version when possible
+
+A set of components for managing component states (including mounting and unmounting) over time, specifically designed with animation in mind.

+/**
+ * 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 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,
+   *  enter?: string,
+   *  enterActive?: string,

+ * 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

+/**
+ * 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'`.

+   * 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'`.

+   * [`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 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,
+     *  enter?: string,
+     *  enterActive?: string,

+/**
+ * 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 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,
+   *  enter?: string,

+ *
+ * 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

+/**
+ * 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'`.
