Mabhenefiti ekudzidza JavaScript (JS) muna 2024, mikana uye maonero

Mabhenefiti ekudzidza JavaScript (JS) muna 2022, mukurumbira nemikana, nei uchifanira kudzidza JS? JavaScript (JS) ndeye prototype-based programming mutauro. Pakutanga, mutauro wakagadzirwa kuitira kuti uwedzere zviwanikwa zveInternet, ndiko kuti, kuita kuti mawebhusaiti apindure sezvinobvira uye nekukurumidza kupindura kumirairo yemushandisi. Izvi zvinosanganisira pop-up windows, mabhatani anoshanda, nekudzvanya pane iyo system inoita chimwe chiito.

JavaScript: inoshanda application, inopa ruzivo rweJS

JavaScript inoshandiswa mumapurojekiti mazhinji ekuvandudza sevha. Sezvo mutemo, mabhesi evatengi, mashandisirwo epamhepo uye zviwanikwa zvewebhu zvakavakwa pahwaro hwekodhi yemutauro uyu wechirongwa. JavaScript inoshandiswa kune zvinotevera zviito uye mabasa:

1. Kuvandudzwa kweyakajairwa yakamisikidzwa mobile application . Aya ndiwo mapurogiramu ehurongwa anovakwa otomatiki panguva yekuvandudza OS.
2. Kuvandudzwa kwesoftware uye hardware chikamu chebasa (backend) .. Mumutauro wepurogiramu iyi, chikamu chemukati chemidziyo yakawanda, mapurogiramu uye mawebsite zvakanyorwa zvakare. Ndiko kuti, nerubatsiro rwekodhi imwe yakanyorwa muJavaScript, unogona kugadzira ese mutengi base uye kugadzira yemukati saiti server.
3. Kuvandudza mapurogiramu emakombiyuta . JS yakashandiswa mukugadzira zvirongwa zvehofisi zvakaita seMicrosoft, Skype, nezvimwe.
4. Kugadzirwa kwekutengesa marobhoti ekutengesa . Sezvo JS iri mutauro uri nyore kudzidza, vatengesi vazhinji vanoda kugadzira robhoti rekutengesa ivo pachavo vanotendeukira kushandisa uyu mutauro wekuronga.

Nei iyo JavaScript programming mutauro yave yakakurumbira uye ichiramba ichiwana mukurumbira: maonero enyanzvi dzine ruzivo

JavaScript ndeimwe yeanonyanya kudiwa-programming mitauro munyika, iri pachinzvimbo chechinomwe muTIOBE index. Vagadziri vezvirongwa vane ruzivo vanocherekedza zvikonzero zvakati kuti zvekumutswa kwemutauro wazvino wechirongwa uye nei uchiramba uchizivikanwa.

Inounza mawebhusaiti mhenyu

Sezvataona pamusoro, nerubatsiro rweJS, webhu saiti inogona kuunzwa mune ine simba, ichimhanyisa uye kurerutsa basa pairi. Pop-up windows, mabhatani anoshanda anoshanda, kana adzvanywa, mumwe murairo unoitwa – zvese izvi zvinoitwa pahwaro hweJava Script chirongwa chekodhi.

Progressive web apps dziri kuwana mukurumbira

PWA (progressive web applications) itekinoroji inosanganisa online sosi uye nharembozha, iyo, semhedzisiro, inotsiva chirongwa che smartphone newebhusaiti. Inoshandiswa zvakanyanya neGoogle Corporation.

Zviri nyore kudzidza

Kunyange paine manuances ekudzidza chero mutauro wechirongwa, kusanganisira JavaScript, zviri nyore kwazvo kudzidza uye kukanganisa kukanganisa. Chero mushandisi, kana achida, achakwanisa kunzwisisa iyo kodhi yekunyora system uye kuvaka zvigadzirwa zvinodiwa pahwaro hwayo.

Nei uchifanira kutarisisa kuJS paunenge uchinyora zvikumbiro, marobhoti kana zvimwe zvinangwa?

Pane zvikonzero zvakawanda zvekushandisa JavaScript:

• huwandu hukuru hweruzivo maererano nekudzidza kwayo, nuances uye basa rinogona kuwanikwa munharaunda yeruzhinji paInternet;
• zvakasiyana-siyana zvezvishandiso zvebasa;
• nharaunda huru uye ine hushamwari iyo ichakubatsira kugadzirisa nyaya dzamuka;
• mutauro wechirongwa uyu unogona kushandiswa munzvimbo dzakapokana zvachose: kunyora base yevatengi, saiti server, mobile application, nezvimwe;
• kudiwa kukuru mumusika wevashandi.

Cherechedza! Iko kumhanya, kuve nyore uye kurongeka kwekodhi yepurogiramu iri kukura. Asi usatya izvi – nekuda kwenharaunda yakakura, kufarira kwevanhu vazhinji mumutauro wechirongwa ichi, zvakasiyana-siyana zvezvishandiso zvebasa, mushandisi wega wega achakwanisa kudzidza nekuzvimiririra kugadzira yavo yega system chigadzirwa.

JavaScript ichava nemukurumbira wakadaro mune ramangwana here?

Iyo tekinoroji maitiro haamire uye, maererano nevanoziva zvirongwa, kwete kare kare pakanga paine matekinoroji anogona kutsiva mamwe ekushanda kwekodhi yepurogiramu mubrowser, asi nhasi vane hutera husina simba kupfuura JS. Izvo zvakakosha kuti makambani makuru mazhinji nhasi anogara achiisa mari mukuvandudza kwemutauro wechirongwa ichi, uye saka haurasikirwe nekukosha kwayo, uchiwedzera kufarirwa uye unoshanda. Nokudaro, maererano nekufanotaura kwemakore mashanu kusvika gumi anotevera, kufarirwa kweJavaScript kuchakura, nokuti kuchine zvakawanda zvinopindirana uye nzvimbo dzakafa paInternet dzinofanira kutariswa. Zvinozoitika zvinotevera zvakaoma kufanotaura nekuda kwehunyanzvi hunogara huripo.

Unyanzvi neruzivo rweJavaScript zvinonyatsodiwa here: zvakanakira uye zvakaipira kudzidza mutauro uyu wekuronga

Vane ruzivo programmers vanopokana kuti mutauro uchave wakakodzera kwenguva yakareba, uye kugona kwayo kwekushanda kunenge kusingagumi. Kune mitauro yakawanda yekuronga, asi JS mune izvi inosiyaniswa nekureruka kwayo, ecosystem uye kuwanikwa. Zvakakosha! Nekudaro, zvakakoshawo kufunga kuti mutauro weJS unogara uchishanduka, uye iwe uchafanirwa kugara uchidzidza matekinoroji matsva uye wobva waashandisa mukuita. Nei uchifanira kudzidza JS:

1. Iyo iri nyore ecosystem, iri pasi peavhareji mushandisi.
2. Wide functionality uye yakakura seti yezvishandiso zvebasa.
3. Unyanzvi hauzove husina maturo, hunogona kubatsira kune zvese muhoro uye nekuda kwezvinangwa zvemunhu.

Zvakaipa zveJS:

1. Tekinoroji nyowani dzinogara dzichipinzwa mumutauro, dzinofanirwa kudzidzwa uye kugona kuzvishandisa mukuita.

Unyanzvi uye hunyanzvi hwemutauro hazvidiwi kune mushandisi ari nyore asingateedzere chinangwa chekunyora zvirongwa, maseva kana asingaronge kubatanidza hupenyu hwake nehurongwa mune ramangwana, zvisinei, kune avo vanoda kunzwisisa nharaunda iyi, izvi zvichave. humwe humbowo hwehunyanzvi.

Kuvandudzwa kwemarobhoti ekutengesa ekutengesa: JavaScript yakakodzera uye chii chinogona kugadzirwa nayo

Vazhinji vatengesi vanoda kuve nemubatsiri wehurongwa hwekutengesa pamasheya, asi vazhinji vavo vanodawo kunyora robhoti vari voga, uye kwete kuraira yakagadzirira-yakagadzirwa. Zvechokwadi, kushingaira kwakadaro kunogamuchirwa, nokuti zvinokwanisika kuisa kushanda kunodiwa muchigadzirwa chako pachako. Nekudaro, ko kana mutengesi asinganzwisise programming mitauro, uye JS flickers nguva nenguva mumarobhoti akakurumbira ekutengesa, yakakodzera here? Nyanzvi dzichataura kuti zviri nani kushandisa C/C ++/C# kunyora mabhoti ekutengesa, asi iyi mitauro yekuronga haisi iyo yakanyanya kupfupika uye iri nyore kudzidza, uye nyika haigumiri ipapo. Kana iwe ukashandisa JS paunenge uchinyora bhoti yekutengesa, ipapo maitiro acho anotora zvishoma, asi kushanda kwemubatsiri,
Mabhenefiti ekushandisa JavaScript paunenge uchinyora robhoti rekutengesa:

1. Pfupi syntax, intuitive kodhi uye yakakura toolkit yebasa rakasununguka.
2. Mutauro wacho ndewepasi rose: kureva kuti, mugadziri achakwanisa kuisa mubhoti yake chero maitiro anodiwa kuti ibudirire kubhidha maitiro.
3. JavaScript ine tarisiro huru yebudiriro, mutauro unogara uchivandudzwa nehunyanzvi hutsva, izvo zvinopa mugadziri mikana yakawanda yekuvandudza robhoti.
4. Mutauro wechirongwa uyu unotsigirwa nevakawanda vemasheya, saka marobhoti anoita basa rawo nemazvo.

Kana uchangotanga kudzidza mashandiro ekutengesa bots, kana kunyange mazviri kana usingaiti. ‘Kunzwisisa, asi unoda kushandisa JS kugadzira chimwe chigadzirwa, usatya kuedza – mutauro uri nyore uye unonzwisisika. Kuronga kutengesa marobhoti mune zvazvino zvinhu: https://youtu.be/JGofLCnwfXk

Zvakanakira uye zvakaipira kudzidza, pamwe nemikana yeJavaScript programming mutauro.

Zvakanakira

Zvikanganiso

Yakapararira uye inoenderana nemapuratifomu akasiyana. Chero browser uye OS inotsigira mutauro uyu. Pakanga pasina matambudziko nekuisa zvikumbiro kana kutanga zviwanikwa zvewebhu paPC kana panharembozha panguva yese iyo kodhi yakashandiswa.	Paunenge uchigadzira, iyo compiler haibatsiri. Ndiko kuti, mugadziri haakwanisi kuziva kana kodhi yakanyorwa ichashanda kusvikira asvika kune imwe mutsara iyo cheki iyi iripo.
Iyo JavaScript application haidi kuisirwa padesktop komputa kana imwe mudziyo – iyo kodhi inonyorwa mubrowser.	Paunenge uchinyora chigadzirwa, iwe uchafanirwa kushandisa zvimwe zviwanikwa. JS haibvumiri kushandura faira, kuisa uye kubuda zviito. Naizvozvo, mugadziri anozofanira kushandisa rechitatu-bato raibhurari mukunyora. Asi izvo zvinogona kuzokundikana mukodhi.
Zviri nyore kudzidza. Zvinoshamisa, nokuti mutauro wepurogiramu uyu unoshanda uye wakakurumbira zvokuti zvingaita sokuti zvinofanira kuva zvakaoma kudzidza, asi kunyange vana kuchikoro vanodzidziswa unyanzvi hwokuishandisa. Iyo syntax uye ecosystem inonzwisisika uye yakajeka, uye nhamba huru yezvishandiso zvebasa zvinongowedzera mikana yemugadziri.	Kudzivirirwa kwakaderera. Kune akawanda mascripting codes aripo paInternet, saka hapana vimbiso yekuti chigadzirwa cheJS hachizobirwa mune ramangwana.
Mutauro wepamusoro. Izvi zvinoreva kuti mumutauro wemutauro uyu pane zvatova kusanganiswa kwezviito, uchishandisa iyo iwe unogona kunyora kodhi nyore nyore. Ndiko kuti, mugadziri haafaniri kunyora chiito chega chega, mutauro uchapa code pachayo. Asi izvi hazvikanganisi kugona kwemushandisi.
Kutsanya mukuita. Zvigadzirwa zvakanyorwa muJavaScript zvinosiyaniswa nehupenyu hwazvo, kukurumidza kupindura uye kuita kwakawanda.

Mabhenefiti ekudzidza JavaScript, ndeapi maficha uye mabhenefiti eJS: https://youtu.be/fqsCkxnXqbk JavaScript yakanakisa multifunctional programming mutauro kwete chete kune vanotanga, asiwo kune vane ruzivo nyanzvi. Iyo syntax uye ecosystem zviri nyore kudzidza, uye huwandu hwakawanda hwezvishandiso huchawedzera sarudzo dzemugadziri. Uye kudzidza mutauro wechirongwa ichi kusimudza hunyanzvi hwako pachako kana kuishandisa kune zvimwe zvinangwa, kana kwete – zviri kumunhu wese kuzvisarudzira.
