Ubwino wophunzirira JavaScript (JS) mu 2022, kutchuka ndi mwayi, chifukwa chiyani muyenera kuphunzira JS? JavaScript (JS) ndi chilankhulo chokhazikitsidwa ndi ma prototype. Poyambirira, chinenerocho chinapangidwa kuti chikhale ndi moyo pa intaneti, ndiko kuti, kupanga mawebusaiti kukhala omvera momwe angathere ndikuyankha mwamsanga malamulo a ogwiritsa ntchito. Izi zikuphatikiza mawindo a pop-up, mabatani ogwira ntchito, podina pomwe dongosololi limachita zinazake.
- JavaScript: ntchito zothandiza, zomwe zimapereka chidziwitso cha JS
- Chifukwa chiyani chinenero cha JavaScript chatchuka kwambiri ndipo chikupitiriza kutchuka: maganizo a akatswiri odziwa zambiri
- Zimapangitsa mawebusayiti kukhala amoyo
- Mapulogalamu apaintaneti opita patsogolo akuyamba kutchuka
- Zosavuta kuphunzira
- Chifukwa chiyani muyenera kulabadira JS polemba ntchito, maloboti kapena pazifukwa zina?
- Kodi JavaScript idzakhala ndi kutchuka koteroko mtsogolomu?
- Kodi maluso ndi chidziwitso cha JavaScript ndizofunikiradi: zabwino ndi zoyipa zophunzirira chilankhulo chokonzekerachi
- Kupanga maloboti ogulitsa malonda: ndi JavaScript yoyenera komanso yomwe ingapangidwe nayo
- Ubwino ndi kuipa kwa kuphunzira, komanso kuthekera kwa chilankhulo cha JavaScript
JavaScript: ntchito zothandiza, zomwe zimapereka chidziwitso cha JS
JavaScript imagwiritsidwa ntchito m’mapulojekiti ambiri opanga ma seva. Monga lamulo, zoyambira zamakasitomala, kugwiritsa ntchito pa intaneti ndi zida zapaintaneti zimamangidwa pamaziko a chilankhulo cha pulogalamu iyi. JavaScript imagwiritsidwa ntchito pazotsatira ndi ntchito zotsatirazi:
- Kupanga mapulogalamu amtundu wamba ophatikizidwa . Awa ndi madongosolo adongosolo omwe amamangidwa okha panthawi yachitukuko cha OS.
- Kupititsa patsogolo mapulogalamu ndi hardware gawo la utumiki (backend) .. M’chinenero chokonzekera ichi, gawo lamkati la zipangizo zambiri, mapulogalamu ndi mawebusaiti amalembedwanso. Ndiye kuti, mothandizidwa ndi kachidindo kamodzi kolembedwa mu JavaScript, mutha kupanga onse kasitomala ndikupanga seva yamkati.
- Kupanga mapulogalamu apakompyuta . JS yagwiritsidwa ntchito popanga mapulogalamu aofesi monga Microsoft, Skype, etc.
- Kupanga maloboti ogulitsa malonda . Popeza JS ndi chilankhulo chosavuta kuphunzira, amalonda ambiri omwe akufuna kupanga loboti yogulitsa okha amagwiritsa ntchito chilankhulo cha pulogalamuyo.
Chifukwa chiyani chinenero cha JavaScript chatchuka kwambiri ndipo chikupitiriza kutchuka: maganizo a akatswiri odziwa zambiri
JavaScript ndi imodzi mwazilankhulo zomwe zimafunidwa kwambiri padziko lonse lapansi, zomwe zili pa nambala 7 pamndandanda wa TIOBE. Olemba mapulogalamu odziwa zambiri amawona zifukwa zingapo zomwe zimachititsa kuti chinenero chamakono chiwukidwe komanso chifukwa chake chikupitiriza kutchuka.
Zimapangitsa mawebusayiti kukhala amoyo
Monga taonera pamwambapa, mothandizidwa ndi JS, gwero la intaneti likhoza kubweretsedwa kukhala lamphamvu, kufulumizitsa ndi kuphweka ntchito pa izo. Mawindo a pop-up, mabatani ogwira ntchito, akakanikizidwa, lamulo linalake limachitidwa – zonsezi zimachitika pamaziko a pulogalamu ya Java Script.
Mapulogalamu apaintaneti opita patsogolo akuyamba kutchuka
PWA (mapulogalamu opitilira pa intaneti) ndiukadaulo womwe umaphatikizira pa intaneti ndi pulogalamu yam’manja, yomwe, chifukwa chake, imalowetsa pulogalamu ya smartphone ndi tsamba lawebusayiti. Imagwiritsidwa ntchito ndi Google Corporation.
Zosavuta kuphunzira
Ngakhale pali ma nuances ophunzirira chilankhulo chilichonse, kuphatikiza JavaScript, ndikosavuta kuphunzira komanso kulolera zolakwika. Wogwiritsa ntchito aliyense, ngati angafune, azitha kumvetsetsa kachitidwe kakulemba kachidindo ndikumanga zomwe akufuna pamaziko ake.
Chifukwa chiyani muyenera kulabadira JS polemba ntchito, maloboti kapena pazifukwa zina?
Pali zifukwa zingapo zogwiritsira ntchito JavaScript:
- zambiri zambiri zokhudzana ndi kafukufuku wake, ma nuances ndi ntchito zitha kupezeka pagulu la anthu pa intaneti;
- zida zambiri zogwirira ntchito;
- gulu lalikulu ndi laubwenzi lomwe lingakuthandizeni kuthetsa mavuto omwe abuka;
- chilankhulo chokonzekerachi chingagwiritsidwe ntchito m’malo otsutsana kwambiri: kulemba makasitomala, seva yamasamba, kugwiritsa ntchito mafoni, ndi zina zotero;
- kufunikira kwakukulu pamsika wantchito.

Zindikirani! Kuthamanga, kumasuka ndi kamangidwe ka ndondomeko ya pulogalamu ikukula. Koma musawope izi – chifukwa cha gulu lalikulu, chidwi cha anthu ambiri m’chinenero ichi cha mapulogalamu, zida zosiyanasiyana zogwirira ntchito, aliyense wogwiritsa ntchito adzatha kuphunzira ndi kupanga okha dongosolo lawo mankhwala.
Kodi JavaScript idzakhala ndi kutchuka koteroko mtsogolomu?
Njira zamakono sizimayima ndipo, malinga ndi olemba mapulogalamu odziwa bwino, osati kale kwambiri panali matekinoloje omwe angalowe m’malo mwa machitidwe a pulogalamu mu osatsegula, koma lero ali ndi mphamvu zochepa kuposa JS. Ndikofunikira kuti makampani akuluakulu ambiri masiku ano azigwiritsa ntchito ndalama zambiri pakupanga chilankhulo cha pulogalamuyo, choncho sichitaya kufunikira kwake, kukhala wotchuka komanso wogwira mtima. Choncho, ponena za kuneneratu kwa zaka zisanu kapena khumi zikubwerazi, kutchuka kwa JavaScript kudzakula, chifukwa pali malo ambiri ndi malo akufa pa intaneti omwe ayenera kuyankhidwa. Zomwe zichitike pambuyo pake ndizovuta kuneneratu chifukwa chaukadaulo womwe umasintha nthawi zonse.
Kodi maluso ndi chidziwitso cha JavaScript ndizofunikiradi: zabwino ndi zoyipa zophunzirira chilankhulo chokonzekerachi
Olemba mapulogalamu odziwa bwino amanena kuti chinenerocho chidzakhala choyenera kwa nthawi yaitali, ndipo mphamvu zake zogwira ntchito zimakhala zopanda malire. Pali zilankhulo zambiri zamapulogalamu, koma JS pankhaniyi imasiyanitsidwa ndi kuphweka kwake, zachilengedwe komanso kupezeka kwake. Zofunika! Komabe, ndikofunikira kuganizira kuti chilankhulo cha JS chikusintha nthawi zonse, ndipo muyenera kuphunzira umisiri watsopano nthawi zonse ndikuzigwiritsa ntchito. Chifukwa chiyani muyenera kuphunzira JS:
- Dongosolo losavuta lachilengedwe, lotengera ngakhale ogwiritsa ntchito wamba.
- Zochita zambiri komanso zida zazikulu zogwirira ntchito.
- Maluso sadzakhala opanda pake, amatha kukhala othandiza pazopeza komanso pazolinga zaumwini.
Kuipa kwa JS:
- Tekinoloje zatsopano zimayambitsidwa nthawi zonse m’chinenerocho, ziyenera kuphunziridwa ndi kuzigwiritsa ntchito pochita.
Maluso ndi luso la chinenero sichifunikira kwa wogwiritsa ntchito wosavuta amene satsatira cholinga cholemba mapulogalamu, ma seva kapena sakukonzekera kugwirizanitsa moyo wake ndi mapulogalamu m’tsogolomu, komabe, kwa iwo amene akufuna kumvetsetsa dera lino, izi zidzakhala. umboni wowonjezera wa ukatswiri.
Kupanga maloboti ogulitsa malonda: ndi JavaScript yoyenera komanso yomwe ingapangidwe nayo
Amalonda ambiri amafuna kukhala ndi wothandizira dongosolo la malonda pa malonda a malonda, koma ambiri a iwo amafunanso kulemba robot paokha, osati kuyitanitsa okonzeka. Zoonadi, changu choterocho ndi cholandirika, chifukwa ndizotheka kuyika ntchito zomwe zimafunikira muzogulitsa zanu. Komabe, bwanji ngati wogulitsa sakumvetsetsa zilankhulo zamapulogalamu, ndipo JS imasinthasintha nthawi ndi nthawi m’maloboti otchuka, kodi ndiyoyenera? Akatswiri anganene kuti ndi bwino kugwiritsa ntchito C/C ++/C# kulemba maloboti ochita malonda, koma zilankhulo zopanga izi sizofupikitsa komanso zosavuta kuphunzira, ndipo dziko silimathera pamenepo. Ngati mugwiritsa ntchito JS polemba bot yamalonda, ndiye kuti njirayi idzatenga nthawi yayitali, koma magwiridwe antchito a wothandizira,
- Syntax yachidule, kachidindo kachidziwitso komanso zida zambiri zogwirira ntchito yabwino.
- Chilankhulochi ndi chapadziko lonse lapansi: ndiye kuti, wopanga azitha kuyika mu bot yake mikhalidwe iliyonse yomwe ili yofunikira kuti achite bwino.
- JavaScript ili ndi chiyembekezo chachikulu cha chitukuko, chinenerocho chimasinthidwa nthawi zonse ndi matekinoloje atsopano, omwe amapatsa wopanga mapulogalamu mwayi wowonjezera robot.
- Chilankhulo chokonzekerachi chimathandizidwa ndi malonda ambiri, kotero ma robot amagwira ntchito yawo moyenera.

Ubwino ndi kuipa kwa kuphunzira, komanso kuthekera kwa chilankhulo cha JavaScript
| Ubwino wake | Zolakwa |
| Chofala komanso chogwirizana ndi nsanja zosiyanasiyana. Msakatuli aliyense ndi OS amathandizira chilankhulochi. Panalibe zovuta pakuyika mapulogalamu kapena kuyambitsa zida zapaintaneti pa PC kapena pa foni yam’manja panthawi yonse yomwe code idagwiritsidwa ntchito. | Popanga, compiler sichithandiza. Ndiko kuti, wopanga mapulogalamu sangathe kudziwa ngati code yolembedwa idzagwira ntchito mpaka atafika pamzere wina umene chekechi chilipo. |
| Pulogalamu ya JavaScript sifunikira kukhazikitsa pakompyuta yapakompyuta kapena chipangizo china – khodiyo imalembedwa mu msakatuli. | Polemba mankhwala, muyenera kugwiritsa ntchito zinthu zina. JS salola kusintha mafayilo, kulowetsa ndi kutulutsa zochita. Chifukwa chake, wopangayo adzayenera kugwiritsa ntchito malaibulale a chipani chachitatu polemba. Koma izi zitha kulephera mu code. |
| Zosavuta kuphunzira. Zodabwitsa, chifukwa chinenero chokonzekerachi ndi chogwira mtima komanso chodziwika bwino moti zingawoneke kuti chiyenera kukhala chovuta kuphunzira, koma ngakhale ana kusukulu amaphunzitsidwa luso lochigwiritsa ntchito. Ma syntax ndi chilengedwe ndizowoneka bwino komanso zomveka, ndipo zida zambiri zogwirira ntchito zimangowonjezera mwayi wa wopanga. | Chitetezo chochepa. Pali ma scripting code ambiri omwe akupezeka pa intaneti, kotero palibe chitsimikizo kuti chopangidwa ndi JS sichidzabedwa mtsogolo. |
| Chilankhulo chapamwamba. Izi zikutanthauza kuti m’dongosolo la chinenerochi muli kale zosakaniza zochita, zomwe mungathe kulemba code mosavuta. Ndiko kuti, woyambitsa sayenera kulembera chochita chilichonse, chinenerocho chidzapereka kachidindo pachokha. Koma izi sizimasokoneza luso la wogwiritsa ntchito. | |
| Mwachangu muzochita. Zogulitsa zolembedwa mu JavaScript zimasiyanitsidwa ndi kukhala achangu, kuyankha mwachangu komanso kusinthasintha kwake. |
Ubwino wophunzirira JavaScript, mawonekedwe ndi maubwino a JS ndi chiyani: https://youtu.be/fqsCkxnXqbk JavaScript ndi chilankhulo chabwino kwambiri chopangira mapulogalamu osati kwa oyamba kumene, komanso kwa akatswiri odziwa zambiri. Syntax ndi chilengedwe ndizosavuta kuphunzira, ndipo zida zambiri zimakulitsa zomwe wopanga angasankhe. Ndipo kuti muphunzire chilankhulo chokonzekera ichi kuti mukweze luso lanu kapena kuzigwiritsa ntchito pazinthu zina, kapena ayi – zili ndi aliyense kusankha yekha.
