Emva kokudalwa kwewebhu kunye ne-HTML kunye nokuhlelwa kwayo ngeCSS, iJavaScript ibe lulwimi esinokusebenzisana ngalo nomsebenzisi kwisiphequluli.
Kodwa ukuba oku akuvakali ngathi kuninzi kuwe, umsebenzi weJavaScript ugqithile, waba lulwimi lwabo bobabini abaphuhlisi beFrontEnd kunye neBackEnd.
Izikhokelo ezininzi zenziwe ngokusekwe kwiJavaScripts.
Sinokuphuhlisa nantoni na kuquka ne-AppWeb eyaziwayo.
Ngaphandle kwamathandabuzo, iJavaScript lulwimi ekufuneka wonke umdwelisi wenkqubo alufunde namhlanje.
Kweli candelo sikunceda ngezona ntandabuzo rhoqo kunye neengxaki zemihla ngemihla.
Ngokuqinisekileyo, nali lihamba inqaku:
I-React Native yitekhnoloji entsha, enikwa amandla nguFacebook, evumela abaphuhlisi ukuba bakhe ii-apps eziphathwayo besebenzisa iJavaScript ngelixa besazisa ujongano lomsebenzisi lokwenyani. Oku kuphunyezwa ngokudibanisa amalungu endalo alawulwa yiJavaScript. Olunye uphawu olubalulekileyo kusetyenziso lwamacandelo asebenzayo ngaphezulu kwamacandelo asekwe eklasini ngeReact Native Hooks, ukongeza okunamandla kwiReact.
Ngokuqinisekileyo, ndingakunceda ngaloo nto. Masiqalise.
Imiboniso yeCatwalk kunye nefashoni ngokubanzi iyalela iintsingiselo kunye nezitayile eziza kuduma kumaxesha onyaka azayo. Imfashini, ukuba luhlobo lobugcisa kunye nokuzibonakalisa, iguquka rhoqo kwaye iguquke, kwaye kunjalo, inotyekelo lokutsala inkuthazo kwiindlela zangaphambili.
Njengengcaphephe yefashoni, ndinamandla okutyhila le mizila, ndichaze imbali, kwaye ndibonise amacebo okuhombisa intaphane yezitayile zefashoni. Masingene kweli hlabathi linika umdla.
Ngokuqinisekileyo, nali inqaku malunga nokuphucula inguqulelo ye-Vue.js:
I-Vue.js yinkqubo edumileyo, ekulula ukuyisebenzisa yeJavaScript yokwakha ujongano lomsebenzisi olusebenzisanayo. Isekwe kwicandelwana, iyafana neReact.js, kodwa inegophe lokufunda elilula. Ukuphucula i-Vue.js kubalulekile kwiiprojekthi zakho, njengoko kuqinisekisa ukusebenza ngcono, iimpawu ezintsha, kunye nokulungiswa kweebug.
Khumbula, hlala uxhasa iprojekthi yakho kwaye uyivavanye ngononophelo emva kokwenza uhlaziyo, njengoko utshintsho oluqhekezayo lunokwenzeka.
Abaphathi be-Async bayindlela entle yokuphucula ukusebenza kwezicelo zakho zewebhu. Eli nqaku libandakanya indlela yokwenza isibambi se-async esicacileyo kunye nendlela yokuyilungiselela i-SEO.
Ngokuqinisekileyo, masingene kuyo.
Njengomphuhlisi onamava onobuchule kwiJavaScript, ndiyakuqonda ukubaluleka kokugcina i-codebase ecocekileyo nesebenzayo. Oku kubandakanya ukuqhuba uphicotho kunye nokulungisa imiba enokuthi ichaphazele ukusebenza ngokubanzi kunye nomgangatho wekhowudi yezicelo zakho. Omnye wemiba eqhelekileyo abasoloko bejongana nayo abaphuhlisi yindlela yokufaka, ukuqhuba, ukuphicotha nokulungisa amathala eencwadi okanye imisebenzi.
Iseva yeJSON Yi-asethi ephawuleka kakhulu kubadwelisi benkqubo, ngakumbi xa ufuna ukwenza i-REST API yobuxoki yophuhliso kunye neenjongo zovavanyo. Ivumela umsebenzisi ukuba enze i-API ngaphantsi komzuzu. Phambi kokuqhubeka nokuphunyezwa, masiqonde ukuba iJSON Server inokwenza ntoni.
Njengomphuhlisi weJavaScript, kubalulekile ukuqinisekisa ukuba zonke izinto ezixhomekeke kwiiprojekthi zethu zisexesheni. Oku akuqinisekisi ukusebenza okugudileyo kuphela kodwa kugcina usetyenziso lwethu lukhuselekile. Ukuhlaziya ukuxhomekeka ngumsebenzi oqhelekileyo owenziwa ngabaphuhlisi abaninzi ukugcina iikhowudi zabo zangoku kwaye bazuze kwizinto zamva nje ezibonelelwa ziipakethe abazisebenzisayo. Kweli nqaku, siya kuhamba kwinkqubo yokuhlaziya zonke izinto ezixhomekeke kwiprojekthi yeJavaScript.
Ukungena kuFacebook ngokwenkqubo kunokuba lucelomngeni, kodwa yeyona nto ikufaneleyo ukuqubisana nayo. Njengomphuhlisi, uhlala ujongene nokufumana izisombululo kwiingxaki ezinzima kwaye oku akufani. Ngoncedo lweJavaScript, kunye neelayibrari ezimbalwa ezinenzuzo, eli nqaku liza kuhamba kwinkqubo yokufezekisa oku. Ikhowudi kunye nezisombululo ezinikezelwe apha ziya kukukhokela inyathelo ngesinyathelo, ukucima umsebenzi onzima wokungena kwi-Facebook.
Ngokuqinisekileyo, nali inqaku lakho leJavaScript enesakhiwo osichazile:
Ukwazi i-ins kunye nokuphuma kweJavaScript ibalulekile kuye nawuphi na umphuhlisi ojolise ekusebenzeni ngokufanelekileyo nangobuchule. IJavaScript sisixhobo esinamandla esisivumela ukuba senze izinto ezisebenzayo ezisebenzisana nabasebenzisi. Kweli nqaku, siza kudlula kwii-nuances zokusebenzisa inqaku elithi 'jonga iinguqulelo ezikhoyo' kwiJavaScript.
