Ukuba umthuthukisi we-JavaScript kuhle ngoba isidingo sabahleli bezinhlelo ezinhle ze-JS sikhula njalo emakethe yezabasebenzi. Namuhla kunezinhlaka eziningi, imitapo yolwazi kanye nezinye izinto ezingasetshenziswa emsebenzini - futhi ngokwezinga elikhulu kufanele sibonge ngokuvula imithombo yalokhu. Kodwa ngesinye isikhathi, umthuthukisi uqala ukuchitha isikhathi esiningi kumaphrojekthi we-JS uma kuqhathaniswa nayo yonke eminye imisebenzi.
Kungenzeka kakhulu ukuthi lokhu kuzoholela emiphumeleni eyinhlekelele yomsebenzi wakho esikhathini esizayo, kodwa awukuqapheli okwamanje. Mina ngokwami ββngenze amanye amaphutha achazwe ngezansi esikhathini esidlule, futhi manje ngifuna ukukuvikela kuwo. Nawa amaphutha kanjiniyela we-JS ayisishiyagalombili angenza ikusasa lakho libe lincane kunokugqama.
Siyakukhumbuza: kubo bonke abafundi be-"Habr" - isaphulelo sama-ruble angu-10 lapho ubhalisa kunoma yisiphi isifundo se-Skillbox usebenzisa ikhodi yephromoshini ethi "Habr".
I-Skillbox iyancoma: Isifundo se-inthanethi semfundo .
Ukusebenzisa i-jQuery
I-jQuery idlale indima enkulu ekuthuthukisweni kwayo yonke i-ecosystem ye-JavaScript. Ekuqaleni, i-JS yayisetshenziselwa ukudala imibukiso yezilayidi nezinhlobo ezihlukahlukene zamawijethi, amagalari ezithombe zamawebhusayithi. I-jQuery yenze kwaba nokwenzeka ukukhohlwa ngezinkinga zokuhambisana kwekhodi phakathi kweziphequluli ezihlukene, ukumisa ukusetshenziswa kwamazinga okukhipha kanye nokusebenza ne-DOM. Ngokulandelayo, lokhu kusize ukwenza lula i-AJAX kanye nezinkinga ngokuhlukana kweziphequluli.
Nokho, namuhla lezi zinkinga azisasebenzi njengakuqala. Iningi lazo laxazululwa ngokumiswa - ngokwesibonelo, lokhu kulanda okukhathazayo kanye nezikhethi ze-API.
Izinkinga ezisele zixazululwa eminye imitapo yolwazi efana ne-React. Imitapo yolwazi inikeza ezinye izici eziningi i-jQuery engenazo.
Lapho usebenza ne-jQuery, ngesinye isikhathi uqala ukwenza izinto ezingajwayelekile, njengokusebenzisa izakhi ze-DOM njengezimo zamanje noma idatha, nokubhala ikhodi eyinkimbinkimbi ngokwesabekayo ukuze nje uthole ukuthi yini engalungile ngesimo sangaphambilini, samanje, nesakusasa se-DOM , ngaphezu kwalokho. ukuqinisekisa ukudlulela ngendlela efanele ezifundazweni ezizayo.
Akukho okuphikisana nokusebenzisa i-jQuery, kodwa zinike isikhathi sokufunda kabanzi mayelana nezinye izindlela zesimanjemanjeβReact, Vue, and Angularβkanye nezinzuzo zazo.
Ukugwema ukuhlolwa kweyunithi
Ngivame ukubona abantu beziba ukuhlolwa kweyunithi kwezinhlelo zabo zokusebenza zewebhu. Konke kuhamba kahle kuze kube yilapho uhlelo lokusebenza luphahlazeka "ngephutha elingalindelekile". Futhi ngalesi sikhathi sithola inkinga enkulu ngoba silahlekelwa isikhathi nemali.
Yebo, uma uhlelo lokusebenza luhlanganisa ngokujwayelekile ngaphandle kokukhiqiza amaphutha, futhi uma seluhlanganisiwe lusebenza, lokhu akusho ukuthi selulungele ukusetshenziswa.
Ukushoda kokuhlolwa kwamukeleka kakhulu noma kancane ezinhlelweni ezincane. Kodwa uma izinhlelo zizinkulu futhi ziyinkimbinkimbi, kunzima ukuzinakekela. Ngakho-ke, ukuhlolwa kuba yinto ebaluleke kakhulu yentuthuko. Ngale ndlela, ukushintsha ingxenye yohlelo lokusebenza ngeke kwephule enye.
Qala ukusebenzisa .
Izinhlaka Zokufunda Ngaphambi KweJavaScript
Ngibaqonda kahle labo okuthi lapho beqala ukwakha uhlelo lwewebhu, baqale ngokushesha ukusebenzisa imitapo yolwazi edumile nezinhlaka ezifana ne-React, Vue noma i-Angular.
Ngangivame ukusho ukuthi udinga ukufunda i-JavaScript kuqala bese emva kwalokho izinhlaka, kodwa manje ngiyaqiniseka ukuthi udinga ukwenza konke ngesikhathi esisodwa. I-JS ishintsha ngokushesha okukhulu, ngakho-ke udinga ukuthola ulwazi oluthile usebenzisa i-React, Vue noma i-Angular ngesikhathi esifanayo nokufunda i-JavaScript.
Lokhu sekuqala ukuthikameza izidingo ezibekwe kumakhandidethi esikhundleni sonjiniyela. Isibonelo, yilokhu engikutholile ngenkathi ngicinga "i-JavaScript" ku-Indeed.
Incazelo yomsebenzi ithi badinga ulwazi lwe-jQuery NE-JavaScript. Labo. Kule nkampani, zombili izingxenye zibaluleke ngokulinganayo.
Nansi enye incazelo ebonisa kuphela izimfuneko "eziyisisekelo":
Futhi lokhu kwenzeka cishe engxenyeni yezikhala engizibhekile. Kodwa-ke, ngikholwa ukuthi isilinganiso esifanele sesikhathi sokufunda i-JS nezinhlaka cishe singama-65% kuye ku-35%, hhayi ama-50 kuye kwangama-50.
Ukungabaza ukujwayelana nomqondo "wekhodi ehlanzekile"
Wonke umthuthukisi onesifiso kufanele afunde ukwenza ikhodi ehlanzekile uma efuna ukuba uchwepheshe. Kuyafaneleka ukuzijwayeza nomqondo "wekhodi ehlanzekile" ekuqaleni komsebenzi wakho. Ngokushesha uma uqala ukulandela lo mqondo, uzosheshe ujwayele ukubhala ikhodi ehlanzekile okulula ukuyinakekela kamuva.
Ngendlela, ukuze uqonde izinzuzo zekhodi enhle nehlanzekile, awudingi ukuzama ukubhala ikhodi embi ngokwakho. Amakhono akho azosebenza ngokuhamba kwesikhathi, emsebenzini, lapho uthuswa ikhodi yomunye umuntu omubi.
Ukuqala umsebenzi kumaphrojekthi amakhulu kusenesikhathi kakhulu
Ekuqaleni komsebenzi wami, ngenza iphutha elikhulu: Ngazama ukuthatha iphrojekthi enkulu ngesikhathi ngingakakulungeli.
Ungase ubuze ukuthi yini engalungile lapha. Kukhona impendulo. Iqiniso liwukuthi uma ungeyena ophakathi noma ophakeme, cishe ngeke ukwazi ukuqedela "iphrojekthi yakho enkulu". Kuzoba nezinto eziningi kakhulu nezinto okufanele zicatshangelwe. Futhi ngeke ukwazi ukubhekana nesimo uma, ekuqaleni komsebenzi wakho, awuzange uhlakulele umkhuba wokubhala "ikhodi ehlanzekile", usebenzisa izivivinyo, izakhiwo eziyingozi, njll.
Ake sithi uchithe isikhathi esiningi kule phrojekthi, awuzange uyiqedele, futhi manje uzama ukuya ezingeni eliphakathi. Bese kuthi ngokuzumayo uyabona ukuthi awukwazi ukukhombisa le khodi kunoma ubani ngoba ayinhle kakhulu futhi idinga ukwenziwa kabusha. Kodwa-ke, uchithe isikhathi esiningi kule "phrojekthi yekhulu leminyaka" futhi manje awunazo izibonelo zomsebenzi omuhle ongawengeza kuphothifoliyo yakho. Futhi ulahlekelwa inhlolokhono eyodwa ngemva kwenye kulabo abakhethiwe abangabonisa umsebenzi wabo, nakuba ungemkhulu kakhulu, kuphothifoliyo.
Kunoma yikuphi, esikhathini esizayo kuzodingeka wenze kabusha, ngoba ikhodi ayilungile kakhulu, futhi nobuchwepheshe obusebenzisile abuyona into oyidingayo. Ngenxa yalokho, uyaqaphela ukuthi kulula ukubhala kabusha yonke into kusukela ekuqaleni kunokuzama ukuyilungisa.
Yiqiniso, konke lokhu kunganezelwa kuphothifoliyo yakho, kodwa umqashi ongase abe khona uzobona amaphutha amaningi lapho futhi afinyelele iziphetho ezikudumazayo.
Ukungabaza ukufunda izakhiwo zedatha nama-algorithms
Ungaphikisana isikhathi eside mayelana nokuthi kufanele uqale nini ukufunda ukwakheka kwedatha nama-algorithms. Abanye abantu baphakamisa ukwenza lokhu ngaphambi kokwazi iJavaScript, abanye emva kwalokho.
Ngikholelwa ukuthi akudingekile ukufunda lokhu ngokuningiliziwe ekuqaleni, kodwa kufanelekile ukuqonda ama-algorithms, ngoba lokhu kuzonikeza ukuqonda okuyisisekelo komsebenzi wezinhlelo zekhompyutha nokubala.
Ama-algorithms ayingxenye ebalulekile yanoma yiziphi izibalo nezinhlelo. Empeleni, izinhlelo zekhompiyutha ngokwazo ziyinhlanganisela yesethi yama-algorithms nedatha ehlelwe ngendlela ethile, yilokho kuphela.
Ukwenqaba umsebenzi womzimba
Kubaluleke kakhulu ukuthi umthuthukisi adlale ezemidlalo. Angiyena umqeqeshi, kodwa ngike ngabuka umzimba wami ushintsha, unyaka nonyaka. Ngakho-ke, ngingakutshela ukuthi ukuntuleka kokuzivocavoca umzimba kuholela kuphi.
Umsebenzi wami wokuqala wawuyinkinga ngenxa yezizathu eziningi, futhi enye yezinkinga yayiwukuthi ngonyaka nje ngathola cishe amakhilogremu angamashumi amabili nambili. Ngabe sengifunda ngenkuthalo i-JavaScript.
Uma ungazivocavoca, usengozini yokuthola isisindo, futhi lokhu kuzoba nemiphumela eminingi emibi: ukukhuluphala ngokweqile, i-migraines (kuhlanganise nezingapheli), umfutho wegazi ophakeme, njll. Uhlu lwezinkinga alupheli ngempela.
Ukuzihlukanisa nomphakathi
Umndeni nabathandekayo babalulekile. Ngokugxila ekufundeni i-JavaScript futhi ubukele phansi ukubaluleka kwempilo yakho yengqondo nengokomzwelo, usengozini yokudangala, ukucasuka, ukungalali kahle, nokunye okuningi.
okutholakele
Ngethemba ukuthi okunye kwalokhu kuwusizo kuwe. Uma uzinakekela namuhla, ngeke kudingeke ukuthi ulungise amaphutha kamuva.
