Nei JavaScript yakave yakakurumbira, tarisiro, yakakodzera kudzidza muna 2024

Kutanga, chii chinonzi JavaScript? Java Script mutauro wekuronga unoshandiswa kuwana akasiyana maapplication. Java script ndeimwe yeanonyanya kufarirwa programming mitauro, uye mukurumbira wayo uri kukura chete. Kana iwe uchida kudzidza zvakawanda nezve nei Java Script iri kuwedzera mukurumbira uye kana zvakakodzera kudzidza JS muna 2022, tarisa chokwadi chiri pazasi.

Ruzivo rwekutanga nezveJS rwaunofanirwa kuziva usati watanga kudzidza JavaScript programming mutauro

JavaScript mutauro wepamusoro-soro wepurogiramu unotsigira akawanda akasiyana maitiro. Zvinoreva boka remitauro yakaturikirwa. Izvo JavaScript inosanganisira:

1. Kukosha kweruzivo kunotsanangurwa nekuverenga kukosha kweiyo nguva dzose, kana hypotenuse.
2. Iyo kodhi yechirongwa kana application inoburitswa kana yawanikwa.
3. Java script mabasa anogona kugoverwa semamwe mabasa akasiyana kubva kune mamwe mafaera, iwe unogona zvakare kuagovera.
4. Nekuda kwekuwanda kweJavascript, inotsigirwa nenhamba huru yemabhurawuza.

ES6 ndeyekuwedzera kutsva kuJavaScript iyo inowedzera kushanda kwayo. Inowedzera rutsigiro rwemuseve basa syntax, kusunungura, kuparadzira uye kuzorora vanoshanda, ma module, uye makirasi.
JavaScript yakapararira uye yakakurumbira, saka nharaunda zhinji dzakagadzira dzakaitenderedza, izvo zvinopa vanogadzira mukana kune mamwe maturusi, akadai se:

• Maraibhurari uye zvimiro.
• Vaunganidzi.
• Maraibhurari ebetsero.
• Static site jenareta.

Uyewo JS:

• inobvumidza iwe kugadzira yemazuva ano yekumberi-yekupedzisira masisitimu uchishandisa React, Angular uye Vue;
• kushandisa React Native kugadzira muchinjika-chikuva maapplication;
• mitambo yakawanda yakanyorwa muJS;
• marobhoti ekutengesa akanyorwa muJavaScript.

Sei JavaScript yakakurumbira uye inokodzera mukurumbira wayo?

Sezvambotaurwa, Javascript inomira seimwe yeanonyanya kufarirwa mitauro yekuronga, zvese maererano nehuwandu hwekushandisa uye mapurojekiti akaitwa pairi, uye kuwanda kwezvikumbiro.

Java isarudzo huru kune vanotanga programmers kuti vapinde mubudiriro. Makambani ari muRussian Federation anotora vanotanga kune avo ewebhu studio. Studios inowanikwa mumaguta makuru uye mumatunhu.

Zvakanakira JavaScript, izvo zvinocherechedzwa nenyanzvi:

• Yekutanga kuwedzera kweJS ndiko kuchinjika kweJS , iyo inobvumidza iwe kugadzira maapplication, kana masayiti ane kudyidzana kukuru.
• Chinhu chechipiri chekuteerera ndechekuvandudzwa kwewebhu web applications , iyo ikozvino iri kuwana mukurumbira. Zviitiko izvi zvave kuteverwa neGoogle. Asi ikozvino PWA iri kuwana mukurumbira, iyo mune ramangwana inogona kutora musika. PWA inogadzirwa uchishandisa JavaScript.

Ndezvipi zvinotarisirwa nemutauro

JS ndeimwe yemitauro inonyanya kudiwa munyika. Zvinoenderana nesevhisi yeTIOB, iri munzvimbo yechinomwe. PaGitHub, mutauro uri munzvimbo yekutanga. Ndiwo mutauro wechipiri unodiwa mushure mePython. Zvose izvi zvinoratidza kuti mutauro une tarisiro huru. JavaScript programming mutauro – zvakanyorwa mariri, maitiro ekuidzidza, marii yavanobhadhara pairi: https://youtu.be/a76uc2FP4yE

Pachave nekudiwa kweJS programmers mune ramangwana

Mukuvandudzwa kwewebhu interfaces, zvikumbiro hazvigone kuita pasina JS. Nokudaro, mukurumbira wayo uchawedzera. Maererano nekufanotaura, pamusoro pemakore gumi anotevera ichave iri kudiwa.

JavaScript zvakanakira nezvayakaipira

Saka, JS yakakodzera kufarirwa here? Zvazvakanakira:

1. Shandisa mukuvandudza webhu – JS chishandiso chinodiwa chine mabasa ese akakodzera, masisitimu, maraibhurari.
2. Kumhanyisa uye kuita – yakakwirira-kumhanya kugadzirisa zvikumbiro kubva kune masaiti inopa mukana wakakura kumutauro uyu. Iye zvakare anoziva maitiro ekugadzirisa chikamu chechikumbiro pasina kugadzira zvikumbiro kune server.
3. Huge ecosystem – huwandu hwezvinhu zvakagadzirwa nemushandisi hwakawedzera zvakanyanya uye hwave kuwanikwa kuti hushandiswe pasina zvirambidzo.
4. Kureruka kwekushandisa – nhamba huru yezvishandiso zvakagadzirirwa kufambisa basa revashandisi, pamwe neyakajeka interface, inoita kuti Javascript iite nyore.
5. Izvo zvinofanirwa kuve zvakaverengerwa kune pluses kukurumidza kudzidza uye kujaira mutauro .

Kufanana nemumwe mutauro, JS haina kukwana – Java Script inewo zvayakaipira:

1. Kushaikwa kwekuverenga nekudhaunirodha mafaira.
2. “Kukanganwirwa kwezvikanganiso” – ichi ndicho chokwadi chokuti mutauro unodarika zvikanganiso uye hauzviratidzi, unonyorawo imwe data maererano nemafungiro ayo. Zvese izvi zvinoratidzwa kare padanho rebasa uye debugging.
3. Kushaikwa kwerutsigiro rwekusvika kure.
4. Inowanikwa zviri nyore kune vanopinda. Nekuda kwekuwanikwa kwemutauro, hazvina kuoma kuisa kodhi yakaipa mairi inokuvadza vashandisi.

Zvisineyi, avo vanoshandisa mutauro uyu vanogara vachiuvandudza mumutauro wavo. nharaunda yevashandisi. Mabhurawuza ari kuita nani pamwe nebasa reJS.

JavaScript game kuvandudzwa

Vanhu vazhinji vanofunga kuti vanoshandisa injini yeC ++ kugadzira mitambo inotonhorera. Izvi zvinogona kunzi ndezvechokwadi, asi kwete zvakakwana, nekuti vanogadzira mapurogiramu emitauro yakasiyana vanotora chikamu mukuvandudza kwemutambo. JavaScript haina musiyano pane izvi. Unogona kugadzira mitambo muJavascript, zvese zviri nyore uye zvakaoma. Muzviitiko zvese izvi, iyo Canvas tekinoroji inoshandiswa, iyo inoita iyo kodhi muHTML5. Peji yeHTML inoshandiswa kumisa tag ye canvas uye kubatanidza iyo JS, uko ndiko kunoitika basa rose. Iyo inodiwa canvas id inotsvakwa muJava faira uye nzira yekushanda nayo inosarudzwa. Pano zvakatsanangurwa matanho ekutanga asati aenderera mberi nekugadzirwa kwemutambo wacho pachako. Nezve mashoma akakurumbira JavaScript mitambo:

1. OnOff – mumutambo uyu unofanirwa kuunza hunhu kumutsara wekupedzisa nekupfuura zvipingamupinyi zvakasiyana nenjodzi nenzira yemabhora ane prickly nemakomba. Neyega yega nhanho yakapedzwa, iwe unozopinda chidimbu chitsva. Mutambo une mazinga makumi maviri nemashanu uye zvinokwanisika kugadzira yako.
2. Underrun mutambo une yakanaka kwazvo pixel art uye yakakura kurira mhedzisiro. Mumutambo, iwe unofanirwa kusvika kurabhoritari nekupfura mutant vavengi. Iwe unofanirwa kusvika ikoko kuti utangezve maLab masisitimu.
3. Super Chrono Portal Mugadziri – mutambo uyu ndewekutanga Super Mario, maunofanirwa kupfuura nematanho ekukunda zvipingamupinyi nevavengi. Imwe neimwe nhanho nyowani, ine makumi matatu mumutambo, inowedzera mechanics matsva uye kushanda. Pane mugadziri wezinga.
4. Offline Paradice mutambo unokurumidza kukurumidza uko dambudziko riri rekusvetuka, kumhanya uye kupwanya zvipingamupinyi. FPS mumutambo inogara ichichengetwa padanho repamusoro, uye iyo autosave ficha ichakubatsira iwe kuchengetedza kufambira mberi kwako. Mutambo uyu uchaperekedzwa nemimhanzi inonakidza, yakanaka kumashure uye yakanaka animation.
5. Raven mutambo wepuzzle umo iwe unofanirwa kugadzirisa makamera kuti usore pane zvisinganzwisisike zvisikwa zvine njodzi murima. Ramba wakatarira kwavari kuti varege kukuuraya.

Mitambo mishoma yakaitwa mumutauro uyu ndiyo yakatsanangurwa pano. Kutaura zvazviri, kune mamwe akawanda.

Nei Uchive Mugadziri weJS muna 2022 – Nei Uchifanira Kudzidza JavaScript, Maonero

Kana usingakwanise kupindura mubvunzo uyu mushure mekuverenga zvese zviri pamusoro, saka chikamu ichi ndechako. Zvikonzero nei JS iri chirongwa chinovimbisa chekudzidza che2022:

1. Mutauro uyu unowanikwa zvakanyanya. Iyo inozivikanwa kwete chete pakati pevanotanga, asiwo pakati pevashandi.
2. Nharaunda huru yeJS. Mutauro unozivikanwa nechikonzero – nhamba huru yekuvandudzwa kwebasa iri nyore nayo inogadzirwa nevashandisi vemutauro uyu. Semuenzaniso: npm ndiye mukuru wepakeji maneja. Uye zvakare, kune akawanda eJava madhairekitori pawebhu ekukubatsira iwe kutanga.
3. Java ndiyo mutauro wemabhurawuza. Ehe, kune analogue yayo WASM, asi kunyangwe haina kunaka kuti ipfuure Java munguva pfupi iri kutevera. Java yakakosha kune vanogadzira webhu.
4. Speed ​​​​uye kunyatsoshanda. Mazhinji emasaiti anozivikanwa akavakirwa paJava, iyo inobatsira zvikuru kwavari. Ivo vane kumhanya kwakanyanya uye kuita, vanodhura zvishoma kune varidzi vadzo, uye zvakare vanogadzirwa uye vanomhanya nekukurumidza.

Kutengesa marobhoti uye mazano muJavaScript

Zvinokosha kucherechedza kuti Java haishandiswe kwete chete mukuvandudza mawebhusaiti nemitambo, asiwo kutanga
kutengesa marobhoti . Kuti uite izvi, Java Script ine zvese zvaunoda:

1. Zviratidziro zvehunyanzvi zvinogona kuwanikwa munharaunda yeruzhinji.
2. Tinkoff library invest-openapi-js-sdk.
3. Zvino ngatitorei zano rakapedzwa setemplate yeimwe shanduko isu pachedu. Iyo template ichave yakapusa 2 SMA zano.
4. Ngatigadzirise zano. Kune izvi, genetics ichashandiswa. Kuti uite izvi, iwe unoda iyo geneticalgorithm raibhurari.

Iyo nzira yekuvandudza yakaoma uye ine minzwa[/ Caption] Kushandisa Java Script uye ane hukama maraibhurari uye masisitimu, kunyangwe Junior JS programmer-mutengesi anogona kunyora iri nyore kutengesa robhoti, achiigadzirisa munzira.
