Impamvu JavaScript yamenyekanye, ibyiringiro, birakwiye kwiga muri 2024

Ubwa mbere, JavaScript ni iki? Java Inyandiko ni ururimi rwa porogaramu rukoreshwa mugushakisha porogaramu zitandukanye. Java inyandiko nimwe mundimi zizwi cyane zo gutangiza porogaramu, kandi gukundwa kwayo kwiyongera gusa. Niba wifuza kumenya byinshi kubyimpamvu Java Script igenda ikundwa kandi niba bikwiye kwiga JS muri 2022, reba ibintu bikurikira.

Amakuru yibanze kuri JS ugomba kumenya mbere yuko utangira kwiga ururimi rwa JavaScript

JavaScript ni ururimi rwo murwego rwohejuru rufasha porogaramu zitandukanye. Yerekeza ku itsinda ryindimi zasobanuwe. Icyo JavaScript ikubiyemo:

1. Agaciro kamakuru agenwa no kubara agaciro gahoraho, cyangwa hypotenuse.
2. Kode ya porogaramu cyangwa porogaramu igaragazwa iyo igeze.
3. Java inyandiko yimikorere irashobora kugenwa nkindi mirimo itandukanye nizindi dosiye, urashobora kandi kuyisangira.
4. Kubera ubwinshi bwa Javascript, ishyigikiwe numubare munini wa mushakisha.

ES6 ninyongera kuri JavaScript yagura imikorere yayo. Ongeraho inkunga kumikorere yimyambi syntax, gukuramo, gukwirakwiza no kuruhuka abakoresha, module, namasomo.
JavaScript irakwirakwiriye kandi irakunzwe, kuburyo abaturage benshi bashinze hafi yayo, biha abitezimbere kubona ibikoresho byinyongera, nka:

• Amasomero n’ibikorwa.
• Abakusanya.
• Amasomero y’abafasha.
• Imashini itanga urubuga.

JS:

• igufasha gukora sisitemu igezweho-sisitemu ukoresheje React, Angular na Vue;
• ukoresheje Reaction Kavukire kugirango ukore porogaramu ihuza imipaka;
• imikino myinshi yanditse muri JS;
• robot zo gucuruza zanditse muri JavaScript.

Kwiga ururimi rwa porogaramu ya JavaScript bigufasha gukemura ibibazo bikurikira [/ caption]

Kuki JavaScript ikunzwe cyane kandi ikwiye kwamamara?

Nkuko byavuzwe haruguru, Javascript iri ku rurimi rumwe mu ndimi zizwi cyane zo gutangiza porogaramu, haba ku mubare w’imikoreshereze n’imishinga ikorerwa kuri yo, ndetse n’inshuro zisabwa.

Java nuburyo bwiza kubatangira programmes kugirango binjire mumajyambere. Amasosiyete yo mu Burusiya ajyana abitangira kuri sitidiyo zabo. Studiyo iherereye mu mijyi minini ndetse no mu turere.

Ibyiza bya JavaScript, byerekanwa nababigize umwuga:

• Icyambere wongeyeho JS nuburyo bworoshye bwa JS , igufasha gukora progaramu, cyangwa imbuga zifite imikoranire ikomeye.
• Ikintu cya kabiri ugomba kwitondera niterambere ryurubuga rwa interineti , kuri ubu rugenda rwamamara. Iterambere ubu rirakurikiranwa cyane na Google. Ariko ubu PWA igenda ikundwa cyane, mugihe kizaza ishobora gufata isoko. PWA yatejwe imbere ikoresheje JavaScript.

Impamvu ugomba kwiga JavaScript

JS iroroshye cyane kwiga, kimwe no guhinduka cyane kandi ntabwo ikaze kumakosa, bitandukanye nizindi ndimi. Niba uri programu ufite uburambe, urashobora guhitamo ururimi wenyine kugirango amakosa adakorwa na gato. Bitewe no kwiyongera kwurubuga rwa porogaramu – Java ntabwo itakaza gukundwa kwayo. Na none, imbuga nyinshi zubatswe mururwo rurimi, rutuma abantu bakorana nabo kubona byoroshye umwanya wa programmer ukwiye muri sosiyete iyo ariyo yose.

Kubona akazi ka javascript biroroshye no kubatangiye, ukurikije umubare wimyanya yabantu [/ caption] Ni ngombwa kandi ko ururimi rudahinduka igihe kizaza, kubera ko ubundi buryo buriho, nubwo busa na JS, ziri kurwego rwarwo n’imikorere baracyakeneye kunoza. Ibigo binini bishora imari mugutezimbere JavaScript, bityo biratera imbere, byerekana ejo hazaza.
JS isanzwe biroroshye nko kurasa [/ caption]

Ni ubuhe buryo bw’ururimi

JS ni rumwe mu ndimi zikenewe cyane ku isi. Nk’uko serivisi ya TIOB ibivuga, iherereye ku mwanya wa karindwi. Kuri GitHub, ururimi ruri mumwanya wambere. Ni ururimi rwa kabiri rwatoranijwe nyuma ya Python. Ibi byose byerekana ko ururimi rufite amahirwe menshi. Ururimi rwa porogaramu ya JavaScript – ibyanditswemo, uburyo bwo kubyiga, uko bishyura: https://youtu.be/a76uc2FP4yE

Ese hazakenerwa abategura JS mugihe kizaza

Mu iterambere ryurubuga, porogaramu ntishobora gukora idafite JS. Kubwibyo, gukundwa kwayo biziyongera. Ukurikije ibiteganijwe, mu myaka 10 iri imbere byanze bikunze bizaba bikenewe. .

JavaScript ibyiza n’ibibi

None, JS irakunzwe cyane? Ibyiza:

1. Koresha mugutezimbere urubuga – JS nigikoresho gikenewe gifite imirimo yose ikwiye, urwego, amasomero.
2. Umuvuduko n’imikorere – byihuse-gutunganya ibyifuzo byurubuga bitanga inyungu nini kururu rurimi. Arazi kandi gutunganya igice cyicyifuzo ataremye ibyifuzo kuri seriveri.
3. Ibinyabuzima binini – umubare wibikoresho byakozwe nabakoresha byiyongereye cyane kandi biboneka kubikoresha nta mbogamizi.
4. Kuborohereza gukoresha – umubare munini wibikoresho byakozwe kugirango byorohereze umurimo wabakoresha, kimwe ninteruro yoroshye, bituma Javascript yoroha bidasanzwe.
5. Bikwiye kandi kwitirirwa plusa yihuta cyane no kumenyera ururimi .

1. Kubura gusoma no gukuramo dosiye.
2. “Kubabarira amakosa” – ibi ni ukuri ko ururimi rusimbuka ibitagenda neza kandi ntirugaragaze, rwandika kandi amakuru akurikije igitekerezo cyarwo. Ibi byose byaragaragaye bimaze kurwego rwakazi no gukemura.
3. Kubura inkunga yo kugera kure.
4. Biroroshye kugera kubacengezi. Bitewe nuburyo bworoshye bwururimi, ntabwo bigoye gushyiramo kode mbi muri yo yangiza abakoresha.

Gutezimbere umukino wa JavaScript

Abantu benshi batekereza ko bakoresha moteri ya C ++ mugukora imikino nziza. Ibi birashobora kwitwa ukuri, ariko ntabwo byuzuye, kuberako abategura indimi zitandukanye bagira uruhare mugutezimbere umukino. JavaScript nayo ntisanzwe kuriyi. Urashobora gukora imikino muri Javascript, byoroshye kandi bigoye. Muri ibyo bihe byombi, tekinoroji ya Canvas irakoreshwa, ikora code muri HTML5. Urupapuro rwa HTML rukoreshwa mugushiraho tagi ya canvas no guhuza JS, niho imirimo yose ibera. Ibisabwa canvas id ishakishwa muri dosiye ya Java kandi inzira yo gukorana nayo iratoranijwe. Hano hasobanuwe ibyiciro byambere mbere yo gukomeza kurema umukino ubwawo. Imikino mike izwi cyane ya JavaScript:

1. OnOff – muri uno mukino ugomba kuzana imico kumurongo wanyuma urenga inzitizi ningaruka zitandukanye muburyo bwimipira n’ibinogo. Hamwe na buri rwego rwuzuye, uzinjiza urwego rushya. Umukino ufite urwego 25 kandi birashoboka gukora urwawe.
2. Underrun numukino ufite pigiseli nziza cyane nubuhanzi bukomeye. Mu mukino, ugomba kugera muri laboratoire urasa abanzi ba mutant. Ugomba kuhagera kugirango usubire muri sisitemu ya laboratoire.
3. Super Chrono Portal Maker – umukino ni Super Mario yumwimerere, aho ugomba kunyura murwego rwo gutsinda inzitizi nabanzi. Buri rwego rushya, murirwo harimo 30 mumikino, wongeyeho ubukanishi bushya nibikorwa. Hariho urwego rwabashushanyije.
4. Offline Paradice ni umukino wihuta aho ikibazo ari ugusimbuka gusa, kwiruka no gusenya inzitizi. FPS mumikino ihora ibitswe kurwego rwohejuru, kandi ibiranga autosave bizagufasha kuzigama iterambere ryawe. Umukino uzajyana numuziki ushimishije, amateka meza na animasiyo nziza.
5. Igikona ni umukino wa puzzle aho ukeneye gusana kamera kugirango utasi ibiremwa byamayobera biteje akaga mu mwijima. Mubakurikirane kugirango batakwica.

Gusa imikino mike yakozwe mururu rurimi yasobanuwe hano. Mubyukuri, hariho nibindi byinshi.

Kuki Kuba JS Iterambere muri 2022 – Impamvu Ukwiye Kwiga JavaScript, Ibitekerezo

Niba udashobora gusubiza iki kibazo nyuma yo gusoma ibyo byose byavuzwe haruguru, noneho iki gice ni icyawe. Impamvu zituma JS ari gahunda yo kwiga itanga ikizere muri 2022:

1. Uru rurimi ni rusange. Ntabwo ikunzwe mubatangiye gusa, ahubwo no mubanyamwuga.
2. Umuryango munini wa JS. Ururimi rurazwi kubwimpamvu – umubare munini wogutezimbere kubikorwa byoroshye hamwe nawo byakozwe nabakoresha uru rurimi. Kurugero: npm numuyobozi mukuru wa pake nini. Mubyongeyeho, hari Java nyinshi ziyobora kurubuga kugirango zigufashe gutangira. Urashobora kwiga Java Script muburyo bwimikino [/ caption]
3. Java ni ururimi rwa mushakisha. Nibyo, hariho analogue yayo WASM, ariko nubwo atari byiza bihagije kurenga Java mugihe cya vuba. Java ningirakamaro kubateza urubuga.
4. Umuvuduko no gukora neza. Imbuga nyinshi zizwi zishingiye kuri Java, zibagirira akamaro cyane. Bafite umuvuduko mwinshi nibikorwa, igiciro gito kuri ba nyirabyo, kandi nacyo cyaremewe kandi gikora vuba.

Indimi 15 zo gutangiza porogaramu ukurikije GitHub [/ caption]

Gucuruza robot ningamba muri JavaScript

Birakwiye ko tumenya ko Java idakoreshwa mugutezimbere imbuga nudukino gusa, ahubwo ikoreshwa no gutangiza
robot zubucuruzi . Kugirango ukore ibi, Java Script ifite ibyo ukeneye byose:

1. Ibipimo bya tekiniki bishobora kuboneka murwego rusange.
2. Isomero rya Tinkoff gushora-gufungura-js-sdk.
3. Noneho reka dufate ingamba zuzuye nkicyitegererezo cyo gukomeza guhinduka ubwacu. Inyandikorugero izaba ingamba zoroshye 2 SMA.
4. Reka tunonosore ingamba. Kuri ibi, genetika izakoreshwa. Kugirango ukore ibi, ukeneye isomero rya geneticalgorithm.
