Most commonly\n * it's used to animate the mounting and unmounting of a component, but can also\n * be used to describe in-place transition states as well.\n *\n * ---\n *\n * **Note**: `Transition` is a platform-agnostic base component. If you're using\n * transitions in CSS, you'll probably want to use\n * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)\n * instead. It inherits all the features of `Transition`, but contains\n * additional features necessary to play nice with CSS transitions (hence the\n * name of the component).\n *\n * ---\n *\n * By default the `Transition` component does not alter the behavior of the\n * component it renders, it only tracks \"enter\" and \"exit\" states for the\n * components. It's up to you to give meaning and effect to those states. For\n * example we can add styles to a component when it enters or exits:\n *\n * ```jsx\n * import { Transition } from 'react-transition-group';\n *\n * const duration = 300;\n *\n * const defaultStyle = {\n * transition: `opacity ${duration}ms ease-in-out`,\n * opacity: 0,\n * }\n *\n * const transitionStyles = {\n * entering: { opacity: 0 },\n * entered: { opacity: 1 },\n * };\n *\n * const Fade = ({ in: inProp }) => (\n *
\n * I'm a fade Transition!\n *
\n * )}\n * \n * \n * {state => (\n * // ...\n * )}\n * \n * \n *
\n * );\n * }\n * ```\n *\n * When the button is clicked the component will shift to the `'entering'` state\n * and stay there for 500ms (the value of `timeout`) before it finally switches\n * to `'entered'`.\n *\n * When `in` is `false` the same thing happens except the state moves from\n * `'exiting'` to `'exited'`.\n */\n\nexports.EXITING = EXITING;\n\nvar Transition =\n/*#__PURE__*/\nfunction (_React$Component) {\n _inheritsLoose(Transition, _React$Component);\n\n function Transition(props, context) {\n var _this;\n\n _this = _React$Component.call(this, props, context) || this;\n var parentGroup = context.transitionGroup; // In the context of a TransitionGroup all enters are really appears\n\n var appear = parentGroup && !parentGroup.isMounting ?

Most commonly\n * it's used to animate the mounting and unmounting of a component, but can also\n * be used to describe in-place transition states as well.\n *\n * ---\n *\n * **Note**: `Transition` is a platform-agnostic base component. If you're using\n * transitions in CSS, you'll probably want to use\n * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)\n * instead. It inherits all the features of `Transition`, but contains\n * additional features necessary to play nice with CSS transitions (hence the\n * name of the component).\n *\n * ---\n *\n * By default the `Transition` component does not alter the behavior of the\n * component it renders, it only tracks \"enter\" and \"exit\" states for the\n * components. It's up to you to give meaning and effect to those states. For\n * example we can add styles to a component when it enters or exits:\n *\n * ```jsx\n * import { Transition } from 'react-transition-group';\n *\n * const duration = 300;\n *\n * const defaultStyle = {\n * transition: `opacity ${duration}ms ease-in-out`,\n * opacity: 0,\n * }\n *\n * const transitionStyles = {\n * entering: { opacity: 1 },\n * entered: { opacity: 1 },\n * exiting: { opacity: 0 },\n * exited: { opacity: 0 },\n * };\n *\n * const Fade = ({ in: inProp }) => (\n * \n * {state => (\n * \n * );\n * ```\n *\n * There are 4 main states a Transition can be in:\n * - `'entering'`\n * - `'entered'`\n * - `'exiting'`\n * - `'exited'`\n *\n * Transition state is toggled via the `in` prop. When `true` the component\n * begins the \"Enter\" stage. During this stage, the component will shift from\n * its current transition state, to `'entering'` for the duration of the\n * transition and then to the `'entered'` stage once it's complete. Let's take\n * the following example (we'll use the\n * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):\n *\n * ```jsx\n * function App() {\n * const [inProp, setInProp] = useState(false);\n * return (\n * \n * {state => (\n * \n * ```\n */\n children: PropTypes.oneOfType([PropTypes.func.isRequired, PropTypes.element.isRequired]).isRequired,\n\n /**\n * Show the component; triggers the enter or exit states\n */\n in: PropTypes.bool,\n\n /**\n * By default the child component is mounted immediately along with\n * the parent `Transition` component.

Format of the format string is based on Unicode Technical Standard #35:\n * https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table\n * with a few additions (see note 5 below the table).\n *\n * Not all tokens are compatible.

`HH` and `a` at the same time\n * ```\n *\n * See the compatibility table:

always nominative singular.\n * In `format` function, they will produce different result:\n *\n * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`\n *\n * `format(new

Any sequence of the identical letters is a pattern, unless it is escaped by\n * the single quote characters (see below).\n * If the sequence is longer than listed in table:\n * - for numerical units (`yyyyyyyy`) `parse` will try to match a number\n * as wide as the sequence\n * - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit.\n * These variations are marked with \"2\" in the last column of the table.\n *\n * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.\n * These tokens represent the shortest form of the quarter.\n *\n * 4.

See: https://git.io/fxCyr\n *\n * 7. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.\n * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr\n *\n * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based\n * on the given locale.\n *\n * using `en-US` locale: `P` => `MM/dd/yyyy`\n * using `en-US` locale: `p` => `hh:mm a`\n * using `pt-BR` locale: `P` => `dd/MM/yyyy`\n * using `pt-BR` locale: `p` => `HH:mm`\n *\n * Values will be assigned to the date in the descending order of its unit's priority.\n * Units of an equal priority overwrite each other in the order of appearance.\n *\n * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),\n * the values will be taken from 3rd argument `referenceDate` which works as a context of parsing.\n *\n * `referenceDate` must be passed for correct work of the function.\n * If you're not sure which `referenceDate` to supply, create a new instance of Date:\n * `parse('02/11/2014', 'MM/dd/yyyy', new Date())`\n * In this case parsing will be done in the context of the current date.\n * If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`,\n * then `Invalid Date` will be returned.\n *\n * The result may vary by locale.\n *\n * If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned.\n *\n * If parsing failed, `Invalid Date` will be returned.\n * Invalid Date is a Date, whose time value is NaN.\n * Time value of Date: http://es5.github.io/#x15.9.1.1\n *\n * ### v2.0.0 breaking changes:\n *\n * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).\n *\n * - Old `parse` was renamed to `toDate`.\n * Now `parse` is a new function which parses a string using a provided format.\n *\n * ```javascript\n * // Before v2.0.0\n * parse('2016-01-01')\n *\n * // v2.0.0 onward (toDate no longer accepts a string)\n * toDate(1392098430000) // Unix to timestamp\n * toDate(new Date(2014, 1, 11, 11, 30, 30)) // Cloning the date\n * parse('2016-01-01', 'yyyy-MM-dd', new Date())\n * ```\n *\n * @param {String} dateString - the string to parse\n * @param {String} formatString - the string of tokens\n * @param {Date|Number} referenceDate - defines values missing from the parsed dateString\n * @param {Object} [options] - an object with options.\n * @param {Locale} [options.locale=defaultLocale] - the locale object.

as \"stand-alone\" units, but are different in some languages.\n * \"Formatting\" units are declined according to the rules of the language\n * in the context of a date. \"Stand-alone\" units are always nominative singular:\n *\n * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`\n *\n * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`\n *\n * 2. Any sequence of the identical letters is a pattern, unless it is escaped by\n * the single quote characters (see below).\n * If the sequence is longer than listed in table (e.g. `EEEEEEEEEEE`)\n * the output will be the same as default pattern for this unit, usually\n * the longest one (in case of ISO weekdays, `EEEE`). Default patterns for units\n * are marked with \"2\" in the last column of the table.\n *\n * `format(new Date(2017, 10, 6), 'MMM') //=> 'Nov'`\n *\n * `format(new Date(2017, 10, 6), 'MMMM') //=> 'November'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMM') //=> 'N'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMMM') //=> 'November'`\n *\n * `format(new Date(2017, 10, 6), 'MMMMMMM') //=> 'November'`\n *\n * 3. Some patterns could be unlimited length (such as `yyyyyyyy`).\n * The output will be padded with zeros to match the length of the pattern.\n *\n * `format(new Date(2017, 10, 6), 'yyyyyyyy') //=> '00002017'`\n *\n * 4. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.\n * These tokens represent the shortest form of the quarter.\n *\n * 5. The main difference between `y` and `u` patterns are B.C. years:\n *\n * | Year | `y` | `u` |\n * |------|-----|-----|\n * | AC 1 | 1 | 1 |\n * | BC 1 | 1 | 0 |\n * | BC 2 | 2 | -1 |\n *\n * Also `yy` always returns the last two digits of a year,\n * while `uu` pads single digit years to 2 characters and returns other years unchanged:\n *\n * | Year | `yy` | `uu` |\n * |------|------|------|\n * | 1 | 01 | 01 |\n * | 14 | 14 | 14 |\n * | 376 | 76 | 376 |\n * | 1453 | 53 | 1453 |\n *\n * The same difference is true for local and ISO week-numbering years (`Y` and `R`),\n * except local week-numbering years are dependent on `options.weekStartsOn`\n * and `options.firstWeekContainsDate` (compare [getISOWeekYear]{@link https://date-fns.org/docs/getISOWeekYear}\n * and [getWeekYear]{@link https://date-fns.org/docs/getWeekYear}).\n *\n * 6. Specific non-location timezones are currently unavailable in `date-fns`,\n * so right now these tokens fall back to GMT timezones.\n *\n * 7. These patterns are not in the Unicode Technical Standard #35:\n * - `i`: ISO day of week\n * - `I`: ISO week of year\n * - `R`: ISO week-numbering year\n * - `t`: seconds timestamp\n * - `T`: milliseconds timestamp\n * - `o`: ordinal number modifier\n * - `P`: long localized date\n * - `p`: long localized time\n *\n * 8. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.\n * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://git.io/fxCyr\n *\n * 9. `D` and `DD` tokens represent days of the year but they are ofthen confused with days of the month.\n * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://git.io/fxCyr\n *\n * ### v2.0.0 breaking changes:\n *\n * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).\n *\n * - The second argument is now required for the sake of explicitness.\n *\n * ```javascript\n * // Before v2.0.0\n * format(new Date(2016, 0, 1))\n *\n * // v2.0.0 onward\n * format(new Date(2016, 0, 1), \"yyyy-MM-dd'T'HH:mm:ss.SSSxxx\")\n * ```\n *\n * - New format string API for `format` function\n * which is based on [Unicode Technical Standard #35](https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table).\n * See [this post](https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg) for more details.\n *\n * - Characters are now escaped using single quote symbols (`'`) instead of square brackets.\n *\n * @param {Date|Number} date - the original date\n * @param {String} format - the string of tokens\n * @param {Object} [options] - an object with options.\n * @param {Locale} [options.locale=defaultLocale] - the locale object.
