Pafupifupi pulogalamu iliyonse yolembedwa mu JavaScript imagwira ntchito ndi nthawi kapena masiku mwanjira ina. Pachiyambi, izi zinali zochepa pa Date API yomangidwa. API iyi imaphatikizapo magwiridwe antchito, koma ndizochepa pazomwe ingachite. Malaibulale a chipani chachitatu monga Moment.js, ndi ma API omangidwa pambuyo pake monga Intl APIs ndi Temporal API yatsopano, amawonjezera kusinthasintha kwakukulu pakugwira ntchito ndi nthawi ndi masiku. Kukwera ndi Kugwa Kwakanthawi.js Moment.js ndi laibulale ya JavaScript yokhala ndi zida zamphamvu zogwirira ntchito ndi nthawi ndi masiku. Zimaphatikizapo zomwe zikusowa kuchokera ku API ya Date API, monga kusintha kwa nthawi, ndipo zimapangitsa kuti ntchito zambiri zizikhala zosavuta. Moment imaphatikizanso ntchito zopanga madeti ndi nthawi. Inakhala laibulale yogwiritsidwa ntchito kwambiri m'mapulogalamu osiyanasiyana. Komabe, Moment inalinso ndi zovuta zake. Ndi laibulale yayikulu, ndipo imatha kuwonjezera kukula kwa mtolo wa pulogalamuyo. Chifukwa laibulale samathandizira kugwedezeka kwamitengo (chinthu chazomangamanga zamakono zomwe zimatha kuchotsa magawo osagwiritsidwa ntchito a malaibulale), laibulale yonse ya Moment imaphatikizidwa ngakhale mutagwiritsa ntchito imodzi kapena ziwiri zokha. Nkhani ina ndi Moment ndikuti zinthu zomwe imapanga zimatha kusintha. Kuitana ntchito zina pa chinthu cha Moment kumakhala ndi zotsatira zake ndipo kumasintha mtengo wa chinthucho. Izi zitha kuyambitsa machitidwe osayembekezeka kapena zolakwika. Mu 2020, osamalira a Moment adaganiza zoyika laibulaleyi kuti ikhale yokonza. Palibe kusintha kwatsopano komwe kukuchitika, ndipo osamalira amalimbikitsa kuti asagwiritsidwe ntchito pama projekiti atsopano. Palinso malaibulale ena a JavaScript, monga date-fns, koma pali wosewera watsopano mtawuniyi, API yomangidwa mwachindunji mu JavaScript: Temporal. Ndi mulingo watsopano womwe umadzaza mabowo a Date API yoyambirira komanso kuthetsa zina mwazoletsa zomwe zimapezeka mu Moment ndi malaibulale ena. Kodi Temporal N'chiyani? Temporal ndi nthawi yatsopano ndi tsiku API yomwe ikuwonjezedwa ku muyezo wa ECMAScript, womwe umatanthawuza JavaScript yamakono. Kuyambira pa Marichi 20266, yafika pa Gawo 4 la ndondomeko ya TC39 (komiti yomwe imayang'anira malingaliro ndi zowonjezera ku JavaScript), ndipo idzaphatikizidwa mumtundu wotsatira wa ndondomeko ya ECMAScript. Zakhazikitsidwa kale m'masakatuli angapo: Chrome 144+ ndi Firefox 139+, ndipo Safari ikuyembekezeka kutsatira posachedwa. Polyfill imapezekanso pamasakatuli osagwiritsidwa ntchito ndi Node.js. Temporal API imapanga zinthu zomwe, nthawi zambiri, zimayimira mphindi mu nthawi. Izi zitha kukhala masitampu anthawi zonse komanso nthawi muzoni yanthawi yomwe mwapatsidwa, kapena zitha kukhala zochitika zanthawi zonse za "nthawi yapakhoma" popanda zone yanthawi kapena zambiri zamasiku. Zina mwazinthu zazikulu za Temporal ndi izi:
Nthawi yokhala ndi masiku kapena opanda masiku.Chinthu Chakanthawi chimatha kuyimira nthawi yeniyeni pa deti linalake, kapena nthawi yopanda zidziwitso zatsiku lililonse. Tsiku lenileni, lopanda nthawi, lingathenso kuimiridwa. Thandizo la zone ya nthawi.Zinthu zokhalitsa zimadziwa nthawi zonse ndipo zimatha kusinthidwa kudutsa nthawi zosiyanasiyana. Moment imathandizira magawo anthawi, nawonso, koma imafunikira laibulale yowonjezera yanthawi yanthawi. Kusasunthika.Chinthu cha Temporal chikapangidwa, sichingasinthidwe. Masamu a nthawi kapena zone ya nthawi sizisintha chinthu chomwe chili pansi. M'malo mwake, amapanga chinthu chatsopano cha Temporal. 1-based indexing.Magwero ambiri a nsikidzi ndi Date API (komanso ndi Moment) ndikuti miyezi imakhala ndi ziro. Izi zikutanthauza kuti Januware ndi mwezi 0, osati mwezi wa 1 monga tonse timamvetsetsa m'moyo weniweni. Izi zimakonza izi pogwiritsa ntchito 1-based indexing - Januware ndi mwezi 1. Imamangidwa mu msakatuli.Popeza Temporal ndi API mu msakatuli wokha, sichimawonjezera chilichonse pakukula kwa mtolo wa pulogalamu yanu.
Ndikofunikiranso kuzindikira kuti Date API sikuchoka. Ngakhale Temporal imaposa API iyi, sikuchotsedwa kapena kuchotsedwa ntchito. Mapulogalamu ambiri amatha kusweka ngati asakatuli achotsa mwadzidzidzi Date API. Komabe, kumbukiraninso kuti Moment tsopano imatengedwa ngati pulojekiti yokhazikika pakukonza. M'nkhani yotsalayo, tiwona "maphikidwe" ena osunthira ma code Moment-based kupita ku Temporal API yatsopano. Tiyeni tiyambe kukonzanso! Kupanga Zinthu Za Tsiku Ndi Nthawi Tisanayambe kusintha madeti ndi nthawi, tiyenera kupanga zinthu zowaimira. Kuti mupange chinthu cha Moment chomwe chikuyimira tsiku ndi nthawi, gwiritsani ntchito mphindi. const now = mphindi(); console.log(tsopano); // Moment<2026-02-18T21:26:29-05:00>
Chinthuchi tsopano chikhoza kusinthidwa kapena kusinthidwa momwe chikufunikira.

Chinthu chofunikira kukumbukira pa Mphindi ndikuti chinthu cha Moment nthawi zonse chimaphatikizapo zambiri zokhudza nthawi ndi tsiku. Ngati mumangofunika kugwira ntchito ndi chidziwitso cha nthawi, izi nthawi zambiri zimakhala zabwino, koma zingayambitse khalidwe losayembekezereka muzochitika monga Nthawi Yopulumutsa Masana kapena zaka zodumphadumpha, kumene tsikulo likhoza kukhala ndi zotsatira pa kuwerengera nthawi. Temporal imasinthasintha. Mutha kupanga chinthu chomwe chikuyimira tsiku ndi nthawi yomwe ilipo popanga chinthu cha Temporal.Instant. Izi zikuyimira nthawi yofotokozedwa ndi nthawi kuyambira "nthawi" (pakati pausiku UTC pa Januware 1, 1970). Temporal imatha kutchula nthawi yomweyo munthawi yake ndikulondola kwa nanosecond. const tsopano = Temporal.Now.instant ();
// onani nanoseconds yaiwisi kuyambira nthawiyo console.log(now.epochNanoseconds); // 1771466342612000000n

Temporal.Instant zinthu zitha kupangidwanso pa nthawi ndi tsiku linalake pogwiritsa ntchito njira ya from static.
const myInstant = Temporal.Instant.from('2026-02-18T21:10:00-05:00');
// Konzani nthawi yomweyo muzoni yanthawi yakomweko. Dziwani kuti izi zimangowongolera // kupanga - sikusintha chinthu ngati moment.utc. console.log(myInstant.toString({timeZone:'America/New_York'})); // 2026-02-18T21:10:00-05:00
Mutha kupanganso mitundu ina ya zinthu Zanthawi, kuphatikiza:
Temporal.PlainDate: Tsiku lopanda zambiri za nthawi. Temporal.PlainTime: Nthawi yopanda zambiri zatsiku. Temporal.ZonedDateTime: Tsiku ndi nthawi mu zoni ya nthawi inayake.
Iliyonse mwa izi ili ndi njira yomwe ingatchulidwe ndi chinthu chofotokozera tsiku ndi / kapena nthawi, kapena chingwe cha deti kuti chidule. // Tsiku chabe const lero = Temporal.PlainDate.from({ chaka: 2026, mwezi: 2, // zindikirani kuti tikugwiritsa ntchito 2 mu February tsiku: 18 }); console.log(today.toString()); // 2026-02-18

Kusanthula Takambirana za kupanga kwadongosolo kwa tsiku ndi nthawi. Tsopano tiyeni tiyang'ane pa kugawa. Parsing ndi gawo limodzi pomwe Moment imakhala yosinthika kwambiri kuposa Temporal API yomangidwa. Mutha kulunzanitsa chingwe cha deti pochipereka ku ntchito yanthawi. Ndi mkangano umodzi, Moment ikuyembekeza chingwe cha tsiku la ISO, koma mutha kugwiritsa ntchito mawonekedwe ena ngati mupereka mtsutso wachiwiri wonena za tsiku lomwe likugwiritsidwa ntchito.
const isoDate = mphindi('2026-02-21T09:00:00'); const formattedDate = mphindi('2/21/26 9:00:00', 'M/D/YY h:mm:ss');

console.log(formattedDate); // Moment<2026-02-21T09:00:00-05:00>
M'matembenuzidwe akale, Moment amatha kulingalira bwino kuti adutse zingwe zilizonse zosinthidwa mosasamala. Izi zitha kubweretsa zotsatira zosayembekezereka. Mwachitsanzo, ndi 02-03-2026 February 2 kapena March 3? Pazifukwa izi, mitundu yatsopano ya Moment imawonetsa chenjezo lodziwikiratu ngati litayitanidwa popanda chingwe chamtundu wa ISO (pokhapokha ngati mkangano wachiwiri wokhala ndi mtundu womwe mukufuna utaperekedwanso). Temporal ingotchula chingwe cha deti lopangidwa mwapadera. Chingwechi chiyenera kugwirizana ndi mtundu wa ISO 8601 kapena kukulitsa kwake, RFC 9557. Ngati chingwe cha deti chosagwirizana chipititsidwa ku njira, Temporal idzaponya RangeError.
// Kugwiritsa ntchito chingwe cha tsiku la RFC 9557 const myDate = Temporal.Instant.from('2026-02-21T09:00:00-05:00[America/New_York]'); console.log(myDate.toString({timeZone:'America/New_York'})); // 2026-02-21T09:00:00-05:00

Tikugwiritsanso ntchito kusanthula mosamalitsa, zomwe zikutanthauza kuti Moment siyesa kuyerekeza ndi chingwe cha deti chomwe sichikugwirizana ndi mtunduwo. Ngati chingwe cha deti losakhala la ISO chikadutsa, zipangitsa kuti tsiku likhale losavomerezeka, ndipo titaya cholakwika. Kukhazikitsa kwa Temporal kumawoneka kofanana, koma kuli ndi zosiyana zingapo.
ntchito getEventTimes(inputString, userTimeZone, targetTimeZone) { // 1. Sulani zolowetsazo mu Instant, kenako pangani // a ZonedDateTime m'malo ogwiritsa ntchito. const instant = Temporal.Instant.from(inputString); const eventTime = instant.toZonedDateTimeISO(userTimeZone);
// 2. Sinthani kukhala malo omwe mukufuna // Izi zimangobweza chinthu CHATSOPANO; 'EventTime' ndi yotetezeka. const targetTime = eventTime.withTimeZone(targetTimeZone);

Ndi Moment, tiyenera kufotokoza momveka bwino mtundu wa zingwe zomwe zatuluka. Mosasamala za komwe wogwiritsa ntchito ali kapena komweko, nthawi za chochitikacho nthawi zonse zizisinthidwa monga Mar 5, 2026, 3:00:00pm EST. Komanso, sitiyenera kutaya chosiyana. Ngati chingwe chosavomerezeka chaperekedwa ku Temporal.Instant.from, Temporal idzasiya ife. Chinthu chimodzi choyenera kudziwa ndikuti ngakhale mutayimitsa mosamalitsa, mtundu wa Moment umakhala wofewa. Temporal imafuna kusintha kwa nthawi kumapeto kwa chingwe. Muyeneranso kuzindikira kuti popeza tikugwiritsa ntchito navigator.language, code iyi idzangoyenda mu malo osatsegula, monga woyendetsa sitimayo sakufotokozedwa mu Node.js chilengedwe. Kukhazikitsa Kwakanthawi kumagwiritsa ntchito malo omwe asakatuli ali pano (navigator.language), kotero wogwiritsa ntchito azitha kupeza nthawi ya zochitika mosinthidwa malinga ndi nthawi yake. M'dera la en-US, izi ndi Mar 5, 2026, 3:00:00 pm EST. Komabe, ngati wogwiritsa ntchito ali ku London, mwachitsanzo, nthawi zazochitika zidzasinthidwa kukhala 5 Mar 2026, 15:00:00 GMT-5. Chidule
Zochita Moment.js Zanthawi Nthawi yapano mphindi () Temporal.Now.zonedDateTimeISO() Kusintha kwa ISO mphindi (str) Temporal.Instant.kuchokera(str) Onjezani nthawi .add (7, 'masiku') (amasintha) .add({masiku: 7}) (chinthu chatsopano) Kusiyana .diff(zina, 'maola') .kuyambira(zina).maola Zone ya nthawi .tz('Zone/Name') .withTimeZone('Zone/Name')
Poyang'ana koyamba, kusiyanako kungakhale kosiyana pang'ono (komanso pa Temporal, nthawi zina mawu omveka kwambiri komanso okhwima), koma pali maubwino angapo ogwiritsira ntchito Temporal over Moment.js:
Kufotokozera momveka bwino kumatanthauza zochepa zodabwitsa ndi nsikidzi zosakonzekera. Mphindi ingawoneke ngati yochepetsetsa, koma imaphatikizapo "zongopeka," zomwe nthawi zina zingayambitse madeti olakwika. Ngati mupatsa Temporal china chake chosavomerezeka, chimasokoneza. Ngati code ikugwira ntchito, mukudziwa kuti muli ndi tsiku lovomerezeka. Mphindi imatha kuwonjezera kukula kwakukulu pamtolo wa pulogalamuyo, makamaka ngati mukugwiritsa ntchito phukusi lanthawi yanthawi. Temporal sichimawonjezera chilichonse (chikangotumizidwa msakatuli wanu). Kusasinthika kumakupatsani chidaliro kuti simudzataya kapena kubweza data mukasintha tsiku ndi ntchito. Kuwonetserako kosiyanasiyana kwa nthawi (Instant, PlainDateTime, ZonedDateTime) kutengera zomwe mukufuna, pomwe Moment nthawi zonse imakhala chomata kuzungulira nthawi ya UTC. Temporal imagwiritsa ntchito ma Intl API popanga ma deti, zomwe zikutanthauza kuti mutha kukhala ndi masanjidwe odziwa zakwawo popanda kutchula zizindikiro.
Zolemba pa Polyfill Monga tanena kale, pali Temporal polyfill yomwe ilipo, yogawidwa ngati npm phukusi lotchedwa @js-temporal/polyfill. Ngati mukufuna kugwiritsa ntchito Temporal lero, mufunika polyfill iyi kuti muthandizire asakatuli ngati Safari omwe sanatumize API pano. Nkhani yoyipa ndi iyi ndikuti idzawonjezera kukula kwa mtolo wanu. Nkhani yabwino ndiyakuti imawonjezerabe zochepa kwambiri kuposa mphindi kapena nthawi yanthawi. Nayi kufananitsa kukula kwa mitolo monga idanenedwera ndi Bundlephobia.com, tsamba lomwe limapereka chidziwitso cha kukula kwa phukusi la npm (dinani pa dzina lililonse la phukusi kuti muwone kusanthula kwa Bundlephobia):
Phukusi Minified Minified & gzipped @js-temporal/polyfill 154.1 kB 44.1 kb mphindi 294.4 kB 75.4 kb mphindi-nthawi 1 MB 114.2 kB
Polyfill idakhalanso ndi zovuta m'mbiri yokhudzana ndi kugwiritsa ntchito kukumbukira, ndipo panthawi yolemba, imadziwika kuti inali mu alpha state. Chifukwa cha izi, simungafune kuzigwiritsa ntchito popanga mpaka zitafika pakukhwima. Nkhani ina yabwino ndiyakuti mwachiyembekezo kuti polyfill sidzafunikanso nthawi yayitali (pokhapokha ngati mukufunika kuthandizira asakatuli akale, inde). Panthawi yolemba, Temporal adatumiza mu Chrome, Edge, ndi Firefox. Sili yokonzeka ku Safari pano, ngakhale ikuwoneka kuti ikupezeka ndi mbendera ya nthawi yothamanga pa Zowonera Zamakono zaposachedwa.
