Izindlela Ezinzima Ze-JavaScript Azihambisani Nezinjongo Zokusebenza Zesikhathi Eside

Ukuthembela kakhulu ku-JavaScript ukuze unike amandla izinhlelo zakho zokusebenza zewebhu kudala isikweletu sokusebenza esihlanganisayo esibukela phansi ulwazi lomsebenzisi, amazinga okusesha, kanye nokwanda kwesikhathi. Nakuba i-JavaScript isalokhu iyithuluzi elibalulekile ekuthuthukisweni kwesimanjemanje, amaqembu ayiphatha njengesixazululo esimisiwe kukho konke ukusebenzisana akhela phezu kwesisekelo esehlisa isithunzi njengoba imikhiqizo yawo ikhula.

E-Mewayz, lapho i-OS yethu yebhizinisi lamamojula angu-207 isebenzela abasebenzisi abangaphezu kuka-138,000 nsuku zonke, sifunde kusenesikhathi ukuthi ukusebenza okusimeme kudinga ukukhetha okwenziwe ngamabomu kwezakhiwo - hhayi nje imibhalo esheshayo. Nakhu ukuthi kungani amasu asindayo e-JavaScript ehluleka esikalini nokuthi amaqembu acabanga phambili kufanele enzeni esikhundleni salokho.

Kungani I-JavaScript Eyeqisayo Ilimaza Ukusebenza Ngokuhamba kwesikhathi?

Yonke ikhilobhayithi ye-JavaScript oyithumela esipheqululini kufanele ilandwe, ihlukaniswe, ihlanganiswe, futhi isetshenziswe. Ngokungafani ne-HTML ne-CSS, iziphequluli ezicubungula ngokuqhubekayo, i-JavaScript ivimba uchungechunge oluyinhloko phakathi nokubulawa. Lokhu kusho ukuthi njengoba uhlelo lwakho lokusebenza lukhula futhi luqongelela imibhalo eminingi, izindleko azikho emgqeni — ziyavela.

Ikhasi elilayisha ngokwamukelekayo ngo-200KB we-JavaScript namuhla liba nokuvilapha ku-600KB ezinyangeni eziyisithupha kamuva. Izengezo zesici, ukuhlanganiswa kwezinkampani zangaphandle, amalabhulali ezibalo, nemibhalo yokuhlola ye-A/B konke kunomthelela ekwandeni kwenqwaba. I-Core Web Vitals ye-Google - ikakhulukazi i-Interaction to Next Paint (INP) kanye neLargest Contentful Paint (LCP) - zijezisa lolu hlobo lokunqwabelana, okunomthelela ngqo ekubonakaleni kwakho kosesho.

Ingozi yangempela ukuthi izakhiwo ze-JavaScript ezinzima zifihla izindleko zazo kuze kube yilapho sekwephuze kakhulu. Ukwehliswa kokusebenza kwenzeka kancane kancane, futhi ngesikhathi amaqembu eqaphela, umzamo wokwenza kabusha odingekayo mkhulu kakhulu.

Ziyini Izindleko Ezifihliwe Zokuthuthukisa I-JavaScript-First?

Ngaphezu kwesivinini sekhasi elingahluziwe, izindlela ezisindayo ze-JavaScript zethula izindleko ezimbalwa ezifihliwe ezihlanganisa umjikelezo wokuphila womkhiqizo:

• Ukungalingani kwedivayisi okukhulisiwe: Amadivayisi asezingeni eliphezulu aphatha imibhalo esindayo ngomusa, kodwa amafoni ebhajethi nezingxenyekazi zekhompuyutha ezindala — asetshenziswa ingxenye enkulu yabasebenzisi bomhlaba wonke — alwa kanzima nezikhathi zokuhlaziya nezokusebenzisa, okudala igebe lokufinyeleleka.
• Izindleko eziphezulu zengqalasizinda: Amashifu okunikezela ohlangothini lweklayenti asebenza esipheqululini, kodwa iziphambeko zokunikezela ohlangothini lweseva ezidingekayo ku-SEO kanye nokusebenza komthwalo kwasekuqaleni kwengeza ingqalasizinda eyinkimbinkimbi nezindleko.
• Ukuhlola nokulungisa amaphutha: I-JavaScript eyengeziwe isho amaphuzu amaningi angaba khona okuhluleka, izimo zohlanga, neziphazamisi zokuphatha zezwe okunzima ukuzikhiqiza futhi kubize ukuzilungisa.
• Ukungqubuzana kokugibela kukanjiniyela: Izakhiwo ze-JavaScript eziyinkimbinkimbi ezinezendlalelo eziningi zokususa zehlisa ijubane amalungu eqembu amasha futhi zengeze ingcuphe yokwethula ukuhlehla.
• Ukunwetshwa kwendawo yokuvikeleka: Sonke iskripthi singase sihlasele. Ukuba sengozini kokubhalwa kwe-cross-site, ukuhlaselwa kwe-supply chain ngokusebenzisa ukuncika, kanye nezingozi zokungcoliswa kwe-prototype konke kukhuphuka ngevolumu ye-JavaScript.

Imininingwane esemqoka: Ikhodi esebenza kakhulu ikhodi ongalokothi uyithumele. Zonke izinqumo ze-JavaScript kufanele ziqale ngombuzo: ingabe lokhu kungafezwa nge-HTML, CSS, noma i-logic yohlangothi lweseva esikhundleni salokho? Amaqembu abuza lo mbuzo ngokungaguquki yilawo agcina izinhlelo zokusebenza ezisheshayo, ezinokwethenjelwa esikalini.

Sifike Kanjani Lapha — Futhi Ibhekephi Imboni?

Inkathi ye-JavaScript-yonke into ivele esidingweni sangempela. Izinhlelo zokusebenza zekhasi elilodwa zithembise okuhlangenwe nakho komsebenzisi okushelelayo, nezinhlaka ezifana ne-Angular, React, ne-Vue zenze ukusebenzisana okuyinkimbinkimbi ohlangothini lweklayenti kufinyeleleke kuwo wonke amathimba okuthuthukisa. Isikhathi esithile, ukuhwebelana kwabonakala kufanelekile.

Kodwa i-pendulum ijikela emuva. Imboni ibona ushintsho olucacile oluya ekwakhiweni kwe-server-first, ukuthuthukiswa okuthuthukayo, namasu okunikezwayo ayingxube. Izinhlaka ezifana ne-Astro, Fresh, neziphindaphindo zakamuva ze-Next.js zigcizelela ukuthunyelwa kwe-JavaScript encane ngokuzenzakalelayo. Ukunyuka kwezingxenye zewebhu nokusebenzisana okusekelwe ku-CSS — imibuzo yesiqukathi, ukugqwayiza okuqhutshwa ukuskrola, isikhethi se-:has() — kufakazela ukuthi inkundla ngokwayo ifinyelela kulokho obekudingeka ngaphambilini.

Abathengisi besiphequluli nabo basayina le ndlela. Ukutshalwa kwezimali kwe-Chrome ku-INP njenge-Core Web Vital, i-Safari's aggressive script throttling, kanye namakhono athuthukisiwe okulayisha ubuvila e-Firefox wonke aklomelisa ama-architecture athambile.

Libukeka Kanjani Isu Lokusebenza Okuzinzile?

Ukwakhela ukusebenza kwesikhathi eside kusho ukwamukela i-JavaScript-conscious kune-JavaScript-filosophy yokuqala. Lokhu akusho ukugwema i-JavaScript ngokuphelele — kusho ukuyisebenzisa ngenhloso nokulinganisa umthelela wayo ngokuqhubekayo.

Qala ngamabhajethi okusebenza. Chaza inani eliphakeme lokulayishwa kwe-JavaScript uhlelo lwakho lokusebenza olungathunyelwa ngomzila ngamunye futhi luwusebenzise ngamapayipi e-CI/CD. Uma isici esisha sizodlula isabelomali, ithimba kufanele lithuthukise ikhodi ekhona ngaphambi kokwengeza okwengeziwe. Lo mkhuba owodwa uvimbela ukuqunjelwa kancane kancane okubulala ukusebenza phakathi nezinyanga neminyaka.

Yamukela isithuthukisi esiqhubekayo njengephethini ezenzakalelayo. Nikeza okuqukethwe okunenjongo kuseva, kufake isitayela nge-CSS, bese ungqimba ukusebenzisana kwe-JavaScript phezulu kuphela lapho kunikeza inani elicacile. Le ndlela iqinisekisa ukuthi uhlelo lwakho lokusebenza lusebenzela wonke umsebenzisi kuwo wonke amadivaysi, nolwazi oluthuthukisiwe lwalabo hardware yabo engabasekela.

Ekugcineni, tshala ekubonakaleni. Idatha ye-Real User Monitoring (RUM) ikutshela ngqo ukuthi i-JavaScript yakho ibathinta kanjani abasebenzisi bangempela kuwo wonke amadivayisi wangempela nezimo zenethiwekhi — hhayi nje ukuthi isebenza kanjani emshinini wakho wokuthuthukisa.

Imibuzo Evame Ukubuzwa

Ingabe lokhu kusho ukuthi izinhlaka ze-JavaScript azilungile ezinhlelweni zebhizinisi?

Lutho neze. Izinhlaka zeJavaScript zingamathuluzi anamandla uma zisetshenziswa ngesiyalo. Inkinga ivela lapho amaqembu ezenzakalelayo e-JavaScript eseceleni kweklayenti ngemisebenzi esingethwe kangcono iseva noma inkundla. Uhlelo lokusebenza lohlaka olwakhiwe kahle olunokwehlukanisa amakhodi, ukulayisha okuvilaphayo, nokunikezwa kohlangothi lweseva kungenza kahle kakhulu. Ukhiye uwukusebenzisa ngamabomu — ukukhetha i-JavaScript lapho ithuthukisa ngempela ulwazi lomsebenzisi futhi ikugweme lapho kukhona ezinye izindlela ezilula.

Ingakanani i-JavaScript eningi kakhulu ohlelweni lokusebenza lwewebhu?

Awukho umkhawulo ojwayelekile, kodwa ucwaningo olusuka ku-Google kanye nedatha yengobo yomlando ye-HTTP luphakamisa ukuthi amakhasi athumela ngaphezu kuka-300-400KB we-JavaScript ecindezelwe aqala ukuzwa ukuwohloka kokusebenza okulinganisekayo kumadivayisi eselula amaphakathi. Okubaluleke kakhulu kunenombolo ephelele ukuthrenda - uma inqwaba ye-JavaScript yakho ikhula ngakho konke ukukhishwa futhi ungenayo inqubo yokuqeda lokho kukhula, ukumzila ongabambeki.

Ingabe inkundla enamamojula angu-207 njenge-Mewayz ingahlala isebenza ngempela?

Yebo, kodwa kudinga ukuzibophezela kwezakhiwo. Kwa-Mewayz, sisebenzisa ukuhlukanisa amakhodi okunolaka ukuze abasebenzisi balayishe kuphela amamojula abawasebenzisa ngokuqhubekayo. Kuhlanganiswe nokunikezelwa kohlangothi lweseva kwemithwalo yokuqala kanye nokulanda kusengaphambili okuhlakaniphile kokuzulazula okulindelekile, i-OS yethu yebhizinisi lamamojula angu-207 iletha okuhlangenwe nakho okusheshayo, okungaguquguquki kuzo zonke izigaba zohlelo. Isikali nokusebenza akuhlukani - kudinga nje ukukhetha okwenziwe ngamabomu kobunjiniyela kusukela osukwini lokuqala.

Usulungele ukuthola inkundla yebhizinisi eyakhelwe ukusebenza esikalini? I-Mewayz ikunikeza amamojula ahlanganisiwe angu-207 — ukusuka ku-CRM nokuphathwa kwephrojekthi kuye kuma-invoyisi kanye ne-HR — ngaphandle kokuphazamiseka. Joyina abasebenzisi abangu-138,000 abaqhuba amabhizinisi abo ngokushesha, kusukela ku-$19/mo. Qalisa nge-Mewayz namuhla.
