Conceptually, it's just a map of units to their quantities, accompanied by some additional configuration and methods for creating, parsing, interrogating, transforming, and formatting them. They can be used on their own or in conjunction with other Luxon types; for example, you can use {@link DateTime#plus} to add a Duration object to a DateTime, producing another DateTime.\n *\n * Here is a brief overview of commonly used methods and getters in Duration:\n *\n * * **Creation** To create a Duration, use {@link Duration.fromMillis}, {@link Duration.fromObject}, or {@link Duration.fromISO}.\n * * **Unit values** See the {@link Duration#years}, {@link Duration#months}, {@link Duration#weeks}, {@link Duration#days}, {@link Duration#hours}, {@link Duration#minutes}, {@link Duration#seconds}, {@link Duration#milliseconds} accessors.\n * * **Configuration** See {@link Duration#locale} and {@link Duration#numberingSystem} accessors.\n * * **Transformation** To create new Durations out of old ones use {@link Duration#plus}, {@link Duration#minus}, {@link Duration#normalize}, {@link Duration#set}, {@link Duration#reconfigure}, {@link Duration#shiftTo}, and {@link Duration#negate}.\n * * **Output** To convert the Duration into other representations, see {@link Duration#as}, {@link Duration#toISO}, {@link Duration#toFormat}, and {@link Duration#toJSON}\n *\n * There's are more methods documented below. In addition, for more information on subtler topics like internationalization and validity, see the external documentation.\n */\nexport default class Duration {\n /**\n * @private\n */\n constructor(config) {\n const accurate = config.conversionAccuracy === \"longterm\" || false;\n let matrix = accurate ?

It contains class and instance methods for creating, parsing, interrogating, transforming, and formatting them.\n *\n * A DateTime comprises of:\n * * A timestamp. Each DateTime instance refers to a specific millisecond of the Unix epoch.\n * * A time zone. Each instance is considered in the context of a specific zone (by default the local system's zone).\n * * Configuration properties that effect how output strings are formatted, such as `locale`, `numberingSystem`, and `outputCalendar`.\n *\n * Here is a brief overview of the most commonly used functionality it provides:\n *\n * * **Creation**: To create a DateTime from its components, use one of its factory class methods: {@link DateTime.local}, {@link DateTime.utc}, and (most flexibly) {@link DateTime.fromObject}. To create one from a standard string format, use {@link DateTime.fromISO}, {@link DateTime.fromHTTP}, and {@link DateTime.fromRFC2822}. To create one from a custom string format, use {@link DateTime.fromFormat}. To create one from a native JS date, use {@link DateTime.fromJSDate}.\n * * **Gregorian calendar and time**: To examine the Gregorian properties of a DateTime individually (i.e as opposed to collectively through {@link DateTime#toObject}), use the {@link DateTime#year}, {@link DateTime#month},\n * {@link DateTime#day}, {@link DateTime#hour}, {@link DateTime#minute}, {@link DateTime#second}, {@link DateTime#millisecond} accessors.\n * * **Week calendar**: For ISO week calendar attributes, see the {@link DateTime#weekYear}, {@link DateTime#weekNumber}, and {@link DateTime#weekday} accessors.\n * * **Configuration** See the {@link DateTime#locale} and {@link DateTime#numberingSystem} accessors.\n * * **Transformation**: To transform the DateTime into other DateTimes, use {@link DateTime#set}, {@link DateTime#reconfigure}, {@link DateTime#setZone}, {@link DateTime#setLocale}, {@link DateTime.plus}, {@link DateTime#minus}, {@link DateTime#endOf}, {@link DateTime#startOf}, {@link DateTime#toUTC}, and {@link DateTime#toLocal}.\n * * **Output**: To convert the DateTime to other representations, use the {@link DateTime#toRelative}, {@link DateTime#toRelativeCalendar}, {@link DateTime#toJSON}, {@link DateTime#toISO}, {@link DateTime#toHTTP}, {@link DateTime#toObject}, {@link DateTime#toRFC2822}, {@link DateTime#toString}, {@link DateTime#toLocaleString}, {@link DateTime#toFormat}, {@link DateTime#toMillis} and {@link DateTime#toJSDate}.\n *\n * There's plenty others documented below. In addition, for more information on subtler topics like internationalization, time zones, alternative calendars, validity, and so on, see the external documentation.\n */\nexport default class DateTime {\n /**\n * @access private\n */\n constructor(config) {\n const zone = config.zone || Settings.defaultZone;\n\n let invalid =\n config.invalid ||\n (Number.isNaN(config.ts) ? new Invalid(\"invalid input\") : null) ||\n (!zone.isValid ? unsupportedZone(zone) : null);\n /**\n * @access private\n */\n this.ts = isUndefined(config.ts) ?

Methods that operate on and return arrays, collections,\n * and functions can be chained together. Methods that retrieve a single value\n * or may return a primitive value will automatically end the chain sequence\n * and return the unwrapped value. Otherwise, the value must be unwrapped\n * with `_#value`.\n *\n * Explicit chain sequences, which must be unwrapped with `_#value`, may be\n * enabled using `_.chain`.\n *\n * The execution of chained methods is lazy, that is, it's deferred until\n * `_#value` is implicitly or explicitly called.\n *\n * Lazy evaluation allows several methods to support shortcut fusion.\n * Shortcut fusion is an optimization to merge iteratee calls; this avoids\n * the creation of intermediate arrays and can greatly reduce the number of\n * iteratee executions. Sections of a chain sequence qualify for shortcut\n * fusion if the section is applied to an array and iteratees accept only\n * one argument. The heuristic for whether a section qualifies for shortcut\n * fusion is subject to change.\n *\n * Chaining is supported in custom builds as long as the `_#value` method is\n * directly or indirectly included in the build.\n *\n * In addition to lodash methods, wrappers have `Array` and `String` methods.\n *\n * The wrapper `Array` methods are:\n * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`\n *\n * The wrapper `String` methods are:\n * `replace` and `split`\n *\n * The wrapper methods that support shortcut fusion are:\n * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,\n * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,\n * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`\n *\n * The chainable wrapper methods are:\n * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,\n * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,\n * `commit`,
