Iqukethe izikhangiso

Mayelana nalolu hlelo lokusebenza

Funda i-React Native ngezincazelo ezimfushane, izibonelo zekhodi ezisebenzayo, kanye nezinselele ezincane. Hlola izifundo ezingu-148 kumamojula ayi-10, vula isibonelo endaweni yokudlala yokubhala ikhodi, bese uyishintsha ukuze uqonde ukuthi isikhombimsebenzisi sisebenza kanjani.

Indlela ecacile kusukela eziyisisekelo ukuya ekuzijwayezeni
Qala ngombhalo, imibono, iziguquguquko, izingxenye, izithombe, nezitayela. Qhubeka ungene kuzakhiwo ze-Flexbox, amafomu, okokufaka umbhalo, izinkinobho, ukusebenzisana kokuthinta, ukuskrola, kanye nohlu. Amamojula akamuva ethula ama-hook, izingxenye ezingasetshenziswa kabusha, ukuphathwa kwesimo, imiqondo yokusebenza, izakhiwo eziphendulayo, kanye namaphrojekthi okuzijwayeza.

Funda umqondo ngaphambi kokuhlela
Isifundo ngasinye sihlanganisa inhloso, ukubuka konke kolimi olulula, imibono eyinhloko, ikhodi, amathiphu asebenzayo, inselelo encane, kanye nemibuzo yokuzibuyekeza. Bheka isibonelo eceleni kwencazelo yaso, bese uvula inguqulo ehlelekayo uma usukulungele ukuzama. Amalebula okuqala, aphakathi, kanye nawokuzijwayeza akusiza uqonde ukuthi isihloko ngasinye simi kuphi enkambweni.

Zama izinguquko zakho
Sebenzisa umhleli we-JavaScript kanye ne-JSX owakhelwe ngaphakathi ukuze ulungise umbhalo, amanani, izitayela, kanye nokuziphatha kwezingxenye. Ukugqamisa i-syntax kanye nezinombolo zomugqa kwenza izibonelo zibe lula ukuzilandela. Ukuhlehlisa nokuphinda wenze kukusiza ukuthi uhlole izinguquko, kuyilapho ikhodi yokusetha kabusha ibuyisela isibonelo sokuqala. Thepha uhlelo lokusebenza oluthi "Run" ukuze uvule ukubuka kuqala kwangaphakathi kohlelo lokusebenza, bese ubuyela ekuhleleni ukuze uzame okunye.

Hlola amaphethini awusizo
Funda okokufaka okulawulwayo, ukuqinisekiswa kwefomu, ukubonakala kwephasiwedi, izibali zezinhlamvu, ukuhlunga uhlu, izinto ezikhethiwe, kanye nezimo ezingenalutho. Zijwayeze ngama-counter, ama-timer, iwashi elibukhoma, i-temperature converter, i-tip calculator, amakhadi, i-accordion, amathebhu alula, kanye nohlu lwezinto okufanele zenziwe. Lezi yizibonelo zokufunda ezikuvumela ukuthi uhlole ukuthi izingcezu ezincane zesixhumi esibonakalayo zihlangana kanjani.

Thola isifundo osidingayo
Sesha izihloko zezifundo noma unciphise umtapo wolwazi ngemodyuli. Shintsha phakathi kwazo zonke izifundo, izifundo eziqhubekayo, izintandokazi ezigciniwe, kanye nezifundo eziqediwe. Sebenzisa izilawuli Zangaphambilini Nezilandelayo noma uswayiphe phakathi kwezifundo. Uma uvula isifundo kusuka kulabhulali ehlungiwe, ukuzulazula kulandela lokho kukhetha ukuze uhlale nezihloko ozikhethile.

Landelela ukufunda kwakho
Bhukha izifundo ukuze uzibuyekeze bese uzimaka ziqediwe uma usukulungele. Isikrini sasekhaya sibonisa inqubekela phambili yezifundo, ukubalwa okuqediwe nokulondolozwa, kanye nochungechunge lwesifundo. Qhubeka nesifundo sokugcina noma uqhubekele esihlokweni esilandelayo esingaqediwe. Intuthuko kanye namabhukhimakhi kugcinwa endaweni kudivayisi yakho.

Buyela kuzivivinyo zakho
Ukusebenzisa isibonelo kusindisa ikhodi yaso njengohlaka lwendawo lwaleso sifundo. Vula kabusha indawo yokudlala ukuze ubuyisele uhlaka, noma ulusethe kabusha ukuze lubuyele kukhodi yokuqala. Lokhu kwenza kube lula ukuphinda ubuyekeze umqondo ngemva kwekhefu ngaphandle kokushintsha izinto zokuqala.

Khetha ukubukeka okukhululekile
Khetha imodi yokukhanya, imodi emnyama, noma itimu yesistimu yesixhumi sokufunda. Funda umqondo, hlola ikhodi yawo, wenze ushintsho olulodwa olugxile, bese usebenzisa inselelo ukuze uzijwayeze ukuwusebenzisa.

Yenzelwe abafundi, abaqalayo abanentshisekelo yokubhala ikhodi, kanye nabathuthukisi ababuyekeza imiqondo yesixhumi sokuxhumana seselula. Izibonelo zisebenza ekubukeni kuqala okusekelwe kuwebhu; ama-API athile epulatifomu kanye nokuziphatha kungahluka kuhlelo lokusebenza lwendabuko. Uhlelo lokusebenza luqukethe ukukhangisa. Uhlelo lokusebenza oluzimele lwezemfundo; aluhlobene noma aluvunyelwe yiphrojekthi ye-React Native.
