It takes multiple regex/extractor pairs to try in sequence.\n * Extractors can take a \"cursor\" representing the offset in the match to look at. This makes it easy to combine extractors.\n * combineExtractors() does the work of combining them, keeping track of the cursor through multiple extractions.\n * Some extractions are super dumb and simpleParse and fromStrings help DRY them.\n */\n\nconst ianaRegex = /[A-Za-z_+-]{1,256}(?::?\\/[A-Za-z0-9_+-]{1,256}(?:\\/[A-Za-z0-9_+-]{1,256})?)?/;\nfunction combineRegexes(...regexes) {\n const full = regexes.reduce((f, r) => f + r.source, \"\");\n return RegExp(`^${full}$`);\n}\nfunction combineExtractors(...extractors) {\n return m => extractors.reduce(([mergedVals, mergedZone, cursor], ex) => {\n const [val, zone, next] = ex(m, cursor);\n return [{\n ...mergedVals,\n ...val\n }, zone || mergedZone, next];\n }, [{}, null, 1]).slice(0, 2);\n}\nfunction parse(s, ...patterns) {\n if (s == null) {\n return [null, null];\n }\n for (const [regex, extractor] of patterns) {\n const m = regex.exec(s);\n if (m) {\n return extractor(m);\n }\n }\n return [null, null];\n}\nfunction simpleParse(...keys) {\n return (match, cursor) => {\n const ret = {};\n let i;\n for (i = 0; i < keys.length; i++) {\n ret[keys[i]] = parseInteger(match[cursor + i]);\n }\n return [ret, null, cursor + i];\n };\n}\n\n// ISO and SQL parsing\nconst offsetRegex = /(?:(Z)|([+-]\\d\\d)(?::?(\\d\\d))?)/;\nconst isoExtendedZone = `(?:${offsetRegex.source}?(?:\\\\[(${ianaRegex.source})\\\\])?)?`;\nconst isoTimeBaseRegex = /(\\d\\d)(?::?(\\d\\d)(?::?(\\d\\d)(?:[.,](\\d{1,30}))?)?)?/;\nconst isoTimeRegex = RegExp(`${isoTimeBaseRegex.source}${isoExtendedZone}`);\nconst isoTimeExtensionRegex = RegExp(`(?:T${isoTimeRegex.source})?`);\nconst isoYmdRegex = /([+-]\\d{6}|\\d{4})(?:-?(\\d\\d)(?:-?(\\d\\d))?)?/;\nconst isoWeekRegex = /(\\d{4})-?W(\\d\\d)(?:-?(\\d))?/;\nconst isoOrdinalRegex = /(\\d{4})-?(\\d{3})/;\nconst extractISOWeekData = simpleParse(\"weekYear\", \"weekNumber\", \"weekDay\");\nconst extractISOOrdinalData = simpleParse(\"year\", \"ordinal\");\nconst sqlYmdRegex = /(\\d{4})-(\\d\\d)-(\\d\\d)/; // dumbed-down version of the ISO one\nconst sqlTimeRegex = RegExp(`${isoTimeBaseRegex.source} ?(?:${offsetRegex.source}|(${ianaRegex.source}))?`);\nconst sqlTimeExtensionRegex = RegExp(`(?: ${sqlTimeRegex.source})?`);\nfunction int(match, pos, fallback) {\n const m = match[pos];\n return isUndefined(m) ? fallback : parseInteger(m);\n}\nfunction extractISOYmd(match, cursor) {\n const item = {\n year: int(match, cursor),\n month: int(match, cursor + 1, 1),\n day: int(match, cursor + 2, 1)\n };\n return [item, null, cursor + 3];\n}\nfunction extractISOTime(match, cursor) {\n const item = {\n hours: int(match, cursor, 0),\n minutes: int(match, cursor + 1, 0),\n seconds: int(match, cursor + 2, 0),\n milliseconds: parseMillis(match[cursor + 3])\n };\n return [item, null, cursor + 4];\n}\nfunction extractISOOffset(match, cursor) {\n const local = !match[cursor] && !match[cursor + 1],\n fullOffset = signedOffset(match[cursor + 1], match[cursor + 2]),\n zone = local ? null : FixedOffsetZone.instance(fullOffset);\n return [{}, zone, cursor + 3];\n}\nfunction extractIANAZone(match, cursor) {\n const zone = match[cursor] ?

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 */\nclass Duration {\n /**\n * @private\n */\n constructor(config) {\n const accurate = config.conversionAccuracy === \"longterm\" || false;\n let matrix = accurate ?
