Ukuba ngumphuhlisi weJavaScript kupholile kuba imfuno yabadwelisi beprogram ye-JS ikhula rhoqo kwimarike yabasebenzi. Kule mihla zininzi izikhokelo, amathala eencwadi kunye nezinye izinto ezinokuthi zisetyenziswe emsebenzini - kwaye ubukhulu becala kufuneka sibe nombulelo ngokuvula imithombo yolwazi yoku. Kodwa ngaxa lithile, umphuhlisi uqala ukuchitha ixesha elininzi kwiiprojekthi ze-JS xa kuthelekiswa nayo yonke eminye imisebenzi.
Kusenokwenzeka ukuba oku kuya kukhokelela kwiziphumo ezibi kwikhondo lakho elizayo, kodwa awukayiqondi okwangoku. Mna ngokwam ndenze ezinye zeempazamo ezichazwe ngezantsi kwixesha elidlulileyo, kwaye ngoku ndifuna ukukukhusela kubo. Nazi iimpazamo ezisibhozo zomphuhlisi we-JS ezinokwenza ikamva lakho libe ngaphantsi kunokukhanya.
Siyakhumbuza: kubo bonke abafundi be "Habr" - isaphulelo se-ruble ye-10 xa ubhalisa kuyo nayiphi na ikhosi ye-Skillbox usebenzisa ikhowudi yokuphromotha "Habr".

Ukusebenzisa i-jQuery
I-jQuery idlale indima enkulu kuphuhliso lweJavaScript yonke ecosystem. Ekuqaleni, i-JS yayisetyenziselwa ukwenza imiboniso yezilayidi kunye neentlobo ezahlukeneyo zewijethi, iigalari zemifanekiso yeewebhusayithi. I-jQuery yenze ukuba kube lula ukulibala malunga neengxaki zokuhambelana kwekhowudi phakathi kweziphequluli ezahlukeneyo, ukulinganisa ukusetyenziswa kwamanqanaba okukhupha kunye nokusebenza kunye ne-DOM. Ngokulandelayo, oku kuye kwanceda ukwenza lula i-AJAX kunye nemiba enomahluko webrowser.
Nangona kunjalo, namhlanje ezi ngxaki azikho njengangaphambili. Uninzi lwazo lwasonjululwa ngokubekwa emgangathweni-umzekelo, le nkxalabo yokulanda kunye nabakhethi be-API.
Iingxaki ezishiyekileyo zisonjululwa ngamanye amathala eencwadi afana neReact. Amathala eencwadi abonelela ngezinye izinto ezininzi ijQuery angenayo.
Xa usebenza nge-jQuery, ngaxa lithile uqala ukwenza izinto ezingaqhelekanga, njengokusebenzisa izinto ze-DOM njengeemeko zangoku okanye idatha, kwaye ubhala ikhowudi entsokothileyo kakhulu ukufumanisa ukuba yintoni engalunganga kwimeko yangaphambili, yangoku, kunye neyexesha elizayo ye-DOM, ukongeza. ekuqinisekiseni utshintsho olululo ukuya kumazwe azayo.
Akukho nto ichasene nokusebenzisa i-jQuery, kodwa thatha ixesha lokufunda ngakumbi malunga nezinye iindlela zangoku-React, Vue, kunye ne-Angular-kunye nezibonelelo zabo.
Ukuphepha uvavanyo lweyunithi
Ndihlala ndibona abantu betyeshela iimvavanyo zeyunithi kwizicelo zabo zewebhu. Yonke into ihamba kakuhle de isicelo siphuke "ngempazamo engalindelekanga". Kwaye ngalo mzuzu sifumana ingxaki enkulu kuba siphulukana nexesha kunye nemali.
Ewe, ukuba isicelo siqulunqa ngesiqhelo ngaphandle kokuvelisa iimpazamo, kwaye xa sele siqulunqiwe siyasebenza, oku akuthethi ukuba sikulungele ukusetyenziswa.
Ukunqongophala kovavanyo kuyamkeleka ngakumbi okanye ngaphantsi kwezicelo ezincinci. Kodwa xa iinkqubo zinkulu kwaye zintsonkothile, kunzima ukuzigcina. Ke ngoko, iimvavanyo ziba yinto ebaluleke kakhulu kuphuhliso. Ngale ndlela, ukutshintsha icandelo elinye lesicelo akuyi kwaphula elinye.
Qala ukusebenzisa .
IiNkqubo zokuFunda phambi kweJavaScript
Ndibaqonda kakuhle abo bathi, xa beqala ukuphuhlisa isicelo sewebhu, baqalise ngokukhawuleza ukusebenzisa amathala eencwadi athandwayo kunye nezicwangciso ezifana ne-React, Vue okanye i-Angular.
Ndandidla ngokuthi kufuneka ufunde iJavaScript kuqala kwaye emva koko izikhokelo, kodwa ngoku ndiqinisekile ukuba kufuneka uyenze yonke into ngexesha elinye. I-JS itshintsha ngokukhawuleza okukhulu, ke kufuneka ufumane amava athile usebenzisa iReact, Vue okanye iAngular ngaxeshanye nokufunda iJavaScript.
Oku kuyaqala ukuchaphazela iimfuno ezibekwe kubaviwa besithuba somphuhlisi. Umzekelo, yile nto ndiyifumeneyo xa ndikhangela "iJavaScript" kwi-Ewe.
Inkcazo yomsebenzi ithi bafuna ulwazi lwe-jQuery KUNYE neJavaScript. Ezo. Kule nkampani, omabini amacandelo abaluleke ngokulinganayo.
Nantsi enye inkcazo edwelisa kuphela iimfuno "ezisisiseko":
Kwaye oku kwenzeka kwisiqingatha sezithuba endizijongileyo. Nangona kunjalo, ndiyakholelwa ukuba umlinganiselo ochanekileyo wexesha lokufunda i-JS kunye nesikhokelo malunga ne-65% ukuya kwi-35%, hayi i-50 ukuya kuma-50.
Ukuthandabuza ukuqhelana nombono βwekhowudi ecocekileyoβ
Bonke abaphuhlisi abanqwenelayo kufuneka bafunde ukwenza ikhowudi ecocekileyo ukuba bafuna ukuba yingcaphephe. Kufanelekile ukuba uziqhelanise nombono "wekhowudi ecocekileyo" ekuqaleni komsebenzi wakho. Ngokukhawuleza uqala ukulandela le ngcamango, ngokukhawuleza uza kuqhela ukubhala ikhowudi ecocekileyo ekulula ukuyigcina kamva.
Ngendlela, ukuqonda inzuzo yekhowudi elungileyo kunye necocekileyo, akudingeki ukuba uzame ukubhala ikhowudi embi ngokwakho. Izakhono zakho ziya kuza ngokufanelekileyo kamva, emsebenzini, xa wothuswa yikhowudi embi yomnye umntu.
Ukuqala umsebenzi kwiiprojekthi ezinkulu kwangoko kakhulu
Ekuqaleni komsebenzi wam, ndenza impazamo enkulu: ndazama ukuthatha iprojekthi enkulu xa ndandingekakulungeli.
Ungabuza ukuba yintoni engalunganga apha. Kukho impendulo. Inyaniso kukuba, ukuba awungomntu ophakathi okanye ophezulu, ngoko ngokuqinisekileyo awuyi kukwazi ukugqiba "iprojekthi yakho enkulu". Kuya kubakho izinto ezininzi kakhulu kunye nezinto ezinokuqwalaselwa. Kwaye awuyi kukwazi ukujamelana nayo ukuba, ekuqaleni komsebenzi wakho, awuzange uhlakulele umkhwa wokubhala "ikhowudi ecocekileyo", usebenzisa iimvavanyo, i-architecture enobungozi, njl.
Masithi uchithe ixesha elininzi kule projekthi, khange uyigqibe, kwaye ngoku uzama ukuya kwinqanaba eliphakathi. Kwaye ngequbuliso uyaqonda ukuba awukwazi ukubonisa le khowudi nakubani na kuba ayilunganga kakhulu kwaye ifuna ukulungiswa kwakhona. Nangona kunjalo, uchithe ixesha elininzi kule "projekthi yenkulungwane" kwaye ngoku awunayo imizekelo yomsebenzi omhle wokongeza kwiphothifoliyo yakho. Kwaye ulahlekelwa udliwano-ndlebe emva komnye kwabo baviwa banokubonisa umsebenzi wabo, nangona ungekho mkhulu kakhulu, kwipotfoliyo.
Kwimeko nayiphi na into, kwixesha elizayo kuya kufuneka uhlaziye, kuba ikhowudi ayilungile kakhulu, kwaye iteknoloji oyisebenzisayo ayiyona into oyifunayo. Ngenxa yoko, uyaqonda ukuba kulula ukuphinda ubhale yonke into ukusuka ekuqaleni kunokuzama ukuyilungisa.
Ewe, konke oku kunokongezwa kwipotifoliyo yakho, kodwa umqeshi onokuthi abone iintsilelo ezininzi apho kwaye afike kwizigqibo ezikuphoxayo.
Ukuthandabuza ukufunda izakhiwo zedatha kunye ne-algorithms
Unokuxoxa ixesha elide malunga nokuba kufuneka uqale nini ukufunda isakhiwo sedatha kunye ne-algorithms. Abanye abantu bacebisa ukwenza oku ngaphambi kokuqonda iJavaScript, abanye emva koko.
Ndiyakholelwa ukuba akuyimfuneko ukufunda oku ngokweenkcukacha ekuqaleni, kodwa kuyafaneleka ukuqonda i-algorithms, kuba oku kuya kunika ukuqonda okusisiseko komsebenzi weenkqubo zekhompyutheni kunye nokubala.
Ii-algorithms ziyinxalenye ebalulekileyo yazo naziphi na izibalo kunye neenkqubo. Ngokwenyani, iinkqubo zekhompyuter ngokwazo ziyindibaniselwano yeseti ye-algorithms kunye nedatha eyakhiwe ngendlela ethile, yiyo yonke loo nto.
Ukwala ukwenza umsebenzi womzimba
Kubaluleke kakhulu ukuba umphuhlisi adlale imidlalo. Andingomqeqeshi, kodwa ndibukele umzimba wam utshintsha, unyaka nonyaka. Ngoko ke, ndinokuxelela ukuba ukungabikho kokuzivocavoca umzimba kubangela ntoni.
Umsebenzi wam wokuqala wawuyingxaki ngenxa yezizathu ezininzi, kwaye enye yeengxaki yayikukuba ngonyaka nje ndafumana phantse ishumi elinesibini leekhilogram. Emva koko ndafunda ngokuzimisela iJavaScript.
Ukuba awusebenzisi, unomngcipheko wokufumana ubunzima, kwaye oku kuya kuba nemiphumo emibi emininzi: ukukhuluphala, i-migraines (kubandakanywa nezingapheliyo), uxinzelelo lwegazi oluphezulu, njl. Uluhlu lweengxaki alunasiphelo ngokwenene.
Ukuzahlula ekuhlaleni
Intsapho kunye nabo sibathandayo babalulekile. Ngokuzintyintya ngokufunda iJavaScript kwaye ujongele phantsi ukubaluleka kobomi bakho bengqondo kunye neemvakalelo, ubeka umngcipheko wokudakumba, ukucaphuka, ukungalali kakuhle, nokunye okuninzi.
ezifunyanisiweyo
Ndiyathemba ukuba ezinye zezi zinto ziluncedo kuwe. Ukuba uyazikhathalela namhlanje, akuyi kufuneka ulungise iimpazamo kamva.
