UhloboScript

Uma kukhulunywa ngobuciko bokugqoka izingane, kunenqwaba yezitayela namathrendi okufanele icatshangelwe, okwenza kube umsebenzi ojabulisayo novuselelayo. Kulesi sihloko, sizohlola izitayela ezithile ezidumile zezingane, sinikeze imininingwane ngomlando nefa lalezi zitayela, futhi sinikeze ngisho namathiphu awusizo okuthi ungaxuba kanjani kangcono futhi ufanise izingcezu zezingubo ezihlukene ukuze uthole isiphetho esipholishiwe.

Emhlabeni wezinhlelo, isimo esivame ukuhlangatshezwana naso siyisidingo sokuhlunga izinto eziningi. Lokhu kungase kubonakale kunzima ekuqaleni, ikakhulukazi ngolimi oluthayiphiwe ngokwezibalo njengalo Uhlobo. Nokho, ngendlela efanele, lo msebenzi ungashintsha ube umsebenzi olawulekayo. Lokhu kudlulela ngale kokuhlelwa kwezinhlamvu noma izinombolo; sijula ​​ekuhleleni ngezici ezithile noma izici eziningi zohlelo lwento.

Isixazululo senkinga ngokuvamile sihlanganisa ukusetshenziswa kwendlela ye-array's sort() ngokuhlanganisa nesistimu yohlobo lwe-TypeScript. Nasi isifinyezo esisheshayo sokuthi ungahlunga kanjani izinto eziningi ngempahla 'yegama'.

let arr = [{name: 'Joe'}, {name: 'Bob'}, {name: 'Alice'}];
arr.sort((a, b) => a.name.localeCompare(b.name));

Esibonelweni esingenhla, sisebenzisa indlela ye-JavaScript eyakhelwe ngaphakathi ye-Array.prototype.sort ngokuhlangana nomsebenzi wokuqhathanisa osuselwe ezindaweni.

Impela, nakhu okusalungiswa kwesihloko sakho:

Ukuqonda amandla nokuguquguquka kwezinhlelo ze-Lua kunikeza inani elibalulekile lokuphatha amafayela ngendlela enobuhlakani. Isici esisodwa esibalulekile okufanele siphawulwe yikhono layo lokuhlola ukuthi ifayela likhona yini. Lokhu kusebenza kubaluleke kakhulu ekugwemeni amaphutha noma imiphumela engahlosiwe ngesikhathi sokusebenza kwefayela. Namuhla, sihlose ukuhlukanisa inqubo yokuqinisekisa ubukhona befayela sisebenzisa i-Lua.

Nansi indlela yokuhlela isihloko sakho esiceliwe mayelana nokusabela kwe-“useref”:

I-React ilabhulali eyaziwa emhlabeni wonke yokudala izixhumanisi zomsebenzisi, ikakhulukazi izinhlelo zokusebenza zekhasi elilodwa. Iwumtapo wezincwadi ongasindi futhi ovumelana nezimo oklanyelwe ukuthuthukisa ulwazi lomsebenzisi. Ukuthuthukiswa kwewebhu sekufinyelele kuma-horizons amasha ngezici ezifana nama-Hooks alethwe yi-React. Esinye isici esibalulekile esinjalo, noma ungasicabangela, ihuku elinikezwe i-React lithi useRef. UseRef ngokuvamile isetshenziselwa ukufinyelela amanodi e-DOM noma izakhi ze-React.

Impela, nansi indatshana ende mayelana ne-Font Awesome Angular:

I-Font Awesome iyilabhulali yesithonjana emangalisayo engasetshenziswa ezinhlelweni zethu ze-Angular. Ukufaka i-Font Awesome kunikeza onjiniyela ukufinyelela kumakhulukhulu ezithonjana zamavekhtha ahlukahlukene nezingalawuleki ezingenziwa ngezifiso nge-CSS.

Lokhu kungenza kube lula ngempela ukugcinwa nokuhlelwa kwamaphrojekthi akho e-Angular. Kulo mhlahlandlela, sizofunda ukuthi ungayifaka kanjani i-Font Awesome kuhlelo lwakho lokusebenza lwe-Angular isinyathelo nesinyathelo.

Ukushintsha usayizi wewindi kungase kubonakale kuwumsebenzi ongabalulekile ekuthuthukisweni kwewebhu, kodwa empeleni kuhlanganisa imiqondo embalwa evela ku-JavaScript kanye ne-Typescript, futhi kudlala indima ebalulekile ekuqinisekiseni idizayini ephendulayo nesebenziseka kalula. Kumongo we-UI/UX eguquguqukayo, umsebenzi 'wokushintsha usayizi wewindi' ubalulekile. Izibonelo zansuku zonke zingafaka ibha eseceleni eshwabene lapho iwindi lishintsha usayizi ukuze linikeze indawo yokufunda engenamthungo, noma isithombe segalari esizilungisayo ukuze sigweme ukuhlanekezela. Ukulungiswa kwenziwa ngokusebenza ngokulalela umcimbi wokushintsha usayizi wewindi.

Njengonjiniyela, kungenzeka usebenzise ifolda ethi `node_modules` kumaphrojekthi akho. Lena yingxenye ebalulekile yomhlaba we-JavaScript kanye ne-TypeScript, ikakhulukazi kumaphrojekthi asebenzisa i-Node.js. Lawa `mamojula_e-node` afana ne-DNA yephrojekthi yakho, okuhlanganisa yonke imitapo yolwazi noma okuncikile okudingeka ikhodi yakho isebenze ngendlela efanele. Inkinga ukuthi le folda ingakhula ngokushesha ngosayizi, yenze iphrojekthi yakho ibe nesisindo esikhulu, ikakhulukazi ngokuya ngezinhlelo zokulawula inguqulo. Futhi, kungase kube nenqwaba yokungqubuzana kwenguqulo uma kungaphathwa kahle.

Emphakathini wanamuhla lapho ukugcwala kolwazi kuyinto evamile, ukubhekana nemibhalo ye-HTML kuyinto efanayo. Lonke ikhasi lewebhu lomkhathi we-inthanethi lakhiwe ku-HTML, lidala i-labyrinthine mesh yezinto namathegi. Ukhiye wokuzulazula kule mesh ngendlela ehlelekile nehlelekile ngokusebenzisa i- querySelectorAll indlela kuJavaScript noma, kithi lapha, i-TypeScript.

Ukuguqula amalungu afanayo ku-Typescript kuhilela ukushintsha ngokuyisisekelo ukuhleleka kwezinto ngaphakathi kwamalungu afanayo kusukela ekulandelaneni okukhona kuye kokuphambene. Le nqubo iyingxenye ebalulekile ekuphathweni kwezinhlu, ngakho-ke, ingaba usizo kakhulu ekuxazululeni izinkinga ezihlukahlukene eziyinkimbinkimbi.

The Uhlobo Ulimi luhlanganisa indlela eyakhelwe ngaphakathi yokuhlehlisa amalungu afanayo, eyaziwa ngokuthi umsebenzi we-array.reverse(). Ngempela, sisebenzisa lo msebenzi, singakwazi ukuhlehlisa kalula noma yiliphi iqembu ku-Typescript.

Ukuze ubonise ukusetshenziswa kwayo, cabangela uhlu olulandelayo lwesampula:

let array = [1, 2, 3, 4, 5];

Khona-ke singahlehlisa lolu hlu ngokusebenzisa umsebenzi we-array.reverse() ngendlela elandelayo:

array = array.reverse();

Lokhu kusebenza kuzohlehlisa ukuhleleka kwezakhi ohlwini lwangempela ukuze ukulandelana kwalo kube okuphambene nalokho obekuyikho ngaphambi kokuthi kusetshenziswe umsebenzi.
