Kukhala wopanga JavaScript ndizabwino chifukwa kufunikira kwa opanga mapulogalamu abwino a JS kukukulirakulira pamsika wantchito. Masiku ano pali zomangira zambiri, malaibulale ndi zinthu zina zomwe zingagwiritsidwe ntchito pantchito - ndipo kumlingo waukulu tiyenera kuthokoza potsegula magwero a izi. Koma panthawi ina, wopanga mapulogalamu amayamba kuthera nthawi yochuluka pa ntchito za JS poyerekeza ndi ntchito zina zonse.
Ndizotheka kuti izi zibweretsa zotsatira zoyipa pantchito yanu mtsogolomo, koma simukuzindikira panobe. Ine ndekha ndapanga zina mwa zolakwika zomwe zafotokozedwa pansipa m'mbuyomu, ndipo tsopano ndikufuna kukutetezani kwa iwo. Nawa zolakwika zisanu ndi zitatu zopanga JS zomwe zingapangitse tsogolo lanu kukhala losawoneka bwino.

Kugwiritsa ntchito jQuery
jQuery yathandiza kwambiri pakupanga chilengedwe chonse cha JavaScript. Poyambirira, JS idagwiritsidwa ntchito popanga ma slideshows ndi mitundu yosiyanasiyana ya ma widget, ziwonetsero zazithunzi zamawebusayiti. jQuery idapangitsa kuti zitheke kuyiwala za zovuta zokhudzana ndi kachidindo pakati pa asakatuli osiyanasiyana, kuyimitsa kugwiritsa ntchito milingo yochotsa ndikugwira ntchito ndi DOM. Komanso, izi zidathandizira kufewetsa AJAX ndi zovuta ndi kusiyana kwa msakatuli.
Komabe, masiku ano mavuto amenewa salinso ofunika monga kale. Ambiri aiwo adathetsedwa ndikuyimitsidwa - mwachitsanzo, izi zimakhudzidwa ndi osankha ma API.
Mavuto otsalawo amathetsedwa ndi malaibulale ena monga React. Ma library amapereka zina zambiri zomwe jQuery ilibe.
Mukamagwira ntchito ndi jQuery, nthawi ina mumayamba kuchita zinthu zachilendo, monga kugwiritsa ntchito zinthu za DOM monga momwe zilili panopa kapena deta, ndikulemba zolemba zovuta kwambiri kuti mudziwe chomwe chiri cholakwika ndi zakale, zamakono, ndi zamtsogolo za DOM , kuwonjezera kuonetsetsa kusintha koyenera kumayiko omwe akubwera.
Palibe choletsa kugwiritsa ntchito jQuery, koma patulani nthawi kuti mudziwe zambiri za njira zamakono - React, Vue, ndi Angular - ndi maubwino ake.
Kupewa kuyesa mayunitsi
Nthawi zambiri ndimawona anthu akunyalanyaza mayeso a mayunitsi pamapulogalamu awo a intaneti. Chilichonse chikuyenda bwino mpaka pulogalamuyo itagwa ndi "cholakwika chosayembekezereka". Ndipo panthawi ino timapeza vuto lalikulu chifukwa tikutaya nthawi ndi ndalama.
Inde, ngati pulogalamuyo iphatikizana bwino popanda kutulutsa zolakwika, ndipo ikapangidwa imagwira ntchito, izi sizitanthauza kuti ndiyokonzeka kugwiritsidwa ntchito.
Kupanda kuyezetsa ndikovomerezeka kwambiri kapena kocheperako pamapulogalamu ang'onoang'ono. Koma mapulogalamu akakhala aakulu ndiponso ovuta kuwasamalira. Chifukwa chake, mayeso amakhala chinthu chofunikira kwambiri pakukula. Mwanjira iyi, kusintha chigawo chimodzi cha ntchito sikudzaphwanya china.
Yambani kugwiritsa ntchito .
Kuphunzira Frameworks Pamaso pa JavaScript
Ndimamvetsetsa bwino omwe, akayamba kupanga pulogalamu yapaintaneti, amayamba kugwiritsa ntchito malaibulale odziwika bwino monga React, Vue kapena Angular.
Ndinkanena kuti muyenera kuphunzira JavaScript poyamba ndiyeno mafelemu, koma tsopano ndikukhulupirira kuti muyenera kuchita zonse nthawi imodzi. JS imasintha mwachangu kwambiri, chifukwa chake muyenera kudziwa zambiri pogwiritsa ntchito React, Vue kapena Angular nthawi yomweyo pophunzira JavaScript.
Izi zikuyamba kukhudza zofunikira zomwe zimayikidwa kwa omwe akufuna kukhala ndi udindo wopanga mapulogalamu. Mwachitsanzo, izi ndi zomwe ndidapeza nditafufuza "JavaScript" pa Indeed.
Mafotokozedwe a ntchito akuti amafunikira chidziwitso cha jQuery NDI JavaScript. Iwo. Kwa kampani iyi, zigawo zonse ziwiri ndizofunikira.
Nawa malongosoledwe ena omwe amangotchula zofunikira "zofunikira":
Ndipo izi zimachitika pafupifupi theka la ntchito zomwe ndidaziwona. Komabe, ndikukhulupirira kuti chiΕ΅erengero cholondola cha nthawi yophunzirira JS ndi mafelemu ndi pafupifupi 65% mpaka 35%, osati 50 mpaka 50.
Kukayika kuzolowera lingaliro la "code code"
Aliyense wofuna kupanga ayenera kuphunzira kupanga code yoyera ngati akufuna kukhala katswiri. Ndikoyenera kudzidziwa bwino ndi lingaliro la "code code" kumayambiriro kwa ntchito yanu. Mukangoyamba kutsatira lingaliro ili, mudzazolowera kulemba code yoyera yomwe ndi yosavuta kuyisunga pambuyo pake.
Mwa njira, kuti mumvetse ubwino wa code yabwino ndi yoyera, simukusowa kuyesa kulemba code yoipa nokha. Maluso anu adzabweranso mtsogolo, kuntchito, mukakhumudwa ndi code yoyipa ya munthu wina.
Kuyamba ntchito pa ntchito zazikulu molawirira kwambiri
Kumayambiriro kwa ntchito yanga, ndinalakwitsa kwambiri: ndinayesera kutenga ntchito yaikulu pamene ndinali ndisanakonzekere.
Mutha kufunsa chomwe chavuta apa. Pali yankho. Chowonadi ndi chakuti ngati simuli wapakati kapena wamkulu, ndiye kuti simungathe kumaliza "ntchito yanu yayikulu". Padzakhala zinthu zambiri ndi zinthu zomwe muyenera kuziganizira. Ndipo simungathe kupirira ngati, kumayambiriro kwa ntchito yanu, simunayambe chizolowezi cholemba "code code", pogwiritsa ntchito mayesero, zomangamanga, ndi zina zotero.
Tiyerekeze kuti mudakhala nthawi yayitali pantchitoyi, simunamalize, ndipo tsopano mukuyesera kusuntha mpaka pakati. Ndiyeno mwadzidzidzi mumazindikira kuti simungathe kusonyeza code iyi kwa aliyense chifukwa si yabwino kwambiri ndipo ikufunika kukonzanso. Komabe, mudakhala nthawi yochuluka pa "projekiti ya zaka zana" ndipo tsopano mulibe zitsanzo za ntchito zabwino zomwe mungawonjezere ku mbiri yanu. Ndipo mumataya kuyankhulana kumodzi kwa anthu omwe angasonyeze ntchito yawo, ngakhale si yaikulu kwambiri, mu mbiri.
Mulimonsemo, m'tsogolomu muyenera kukonzanso, chifukwa codeyo si yabwino kwambiri, ndipo matekinoloje omwe mudagwiritsa ntchito sizomwe mukufunikira. Zotsatira zake, mumazindikira kuti n'kosavuta kulembanso chilichonse kuchokera pachiyambi kusiyana ndi kuyesa kukonza.
Inde, zonsezi zikhoza kuwonjezeredwa ku mbiri yanu, koma wogwira ntchitoyo adzawona zofooka zambiri kumeneko ndikufika pamalingaliro omwe akukhumudwitsani.
Kusafuna kuphunzira kapangidwe ka data ndi ma aligorivimu
Mutha kukangana kwa nthawi yayitali za nthawi yomwe muyenera kuyamba kuphunzira kapangidwe ka data ndi ma aligorivimu. Anthu ena amati muchite izi musanaphunzire JavaScript, ena pambuyo pake.
Ndikukhulupirira kuti sikoyenera kuphunzira izi mwatsatanetsatane pachiyambi, koma ndikofunikira kumvetsetsa ma aligorivimu, chifukwa izi zidzapereka chidziwitso chofunikira cha ntchito yamapulogalamu apakompyuta ndi mawerengedwe.
Ma algorithms ndi gawo lofunikira pakuwerengera ndi mapulogalamu aliwonse. M'malo mwake, mapulogalamu apakompyuta okha ndi ophatikizika a ma aligorivimu ndi deta yopangidwa mwanjira inayake, ndizo zonse.
Kukana kuchita masewera olimbitsa thupi
Ndikofunikira kwambiri kuti wopanga masewera azisewera. Ine sindine mphunzitsi, koma ine ndimawona thupi langa likusintha, chaka ndi chaka. Choncho, ndikhoza kukuuzani zomwe kusowa kwa masewera olimbitsa thupi kumayambitsa.
Ntchito yanga yoyamba inali yovuta kwambiri pazifukwa zingapo, ndipo vuto lina linali lakuti mβchaka chimodzi ndinalemera pafupifupi ma kilogalamu khumi ndi awiri. Kenako ndinaphunzira JavaScript mwakhama.
Ngati simuchita masewera olimbitsa thupi, mumakhala pachiwopsezo chonenepa, ndipo izi zitha kukhala ndi zotsatira zoyipa zambiri: kunenepa kwambiri, migraines (kuphatikiza osatha), kuthamanga kwa magazi, ndi zina zambiri. Mndandanda wamavuto ndi wopanda malire.
Kudzipatula pagulu
Banja ndi okondedwa ndi ofunika. Podzipereka pakuphunzira JavaScript ndikuchepetsa kufunikira kwa moyo wanu wamalingaliro ndi malingaliro, mumakhala pachiwopsezo chokhala ndi nkhawa, kukwiya, kusagona bwino, ndi zina zambiri.
anapezazo
Ndikukhulupirira kuti zina mwa izi ndizothandiza kwa inu. Ngati mutadzisamalira lero, simudzasowa kukonza zolakwika pambuyo pake.
