Ukuze siqonde kangcono lolu daba, sizohlaziya ukuthi uyini umholo wonjiniyela weJavaScript bese siqhathanisa amanani emhlabeni jikelele. Kulesi sihloko, sizohlaziya izihloko ezilandelayo.
- Indima yonjiniyela weJavaScript.
- Isidingo sonjiniyela beJavaScript.
- Amaholo wonjiniyela weJavaScript ngokuya ngendawo
- Amaholo wonjiniyela weJavaScript asuselwa eminyakeni yesipiliyoni
- Imiholo yonjiniyela weJavaScript ngokuya ngokuthi inkampani inkulu kangakanani
Indima kanjiniyela weJavaScript
Abathuthukisi beJavaScript basebenzisana nabasebenzisi kanye nabaphathi enkampanini ukuze bahlangabezane nezidingo zabo futhi benze izinguquko ngokwenza ngokwezifiso, ukuklama, kanye nokusebenzisa izici ezintsha.

Isidingo sonjiniyela beJavaScript
Kusukela kuzincazelo ezingenhla, umuntu uzobona ukuthi umakhi weJavaScript uphakathi kwabakleliswe kakhulu emhlabeni wezilimi ezihlela umhlaba wonke. Ngokombiko we-Devskiller 2019, ngezindlela ezivelayo, baqaphele ukuthi izinkampani ezingama-70% zifuna abathuthukisi beJavaScript. Lokhu kukhombisa ukuthi angakanani la makhono akalwe phezulu.
Kolunye ucwaningo olwenziwe yiHackerRank , bahlaziye futhi baphetha ngokuthi isidingo sabathuthukisi beJavaScript sidlula ochwepheshe abatholakalayo kulo mkhakha. Ngokusho kokuhlaziywa kwabo, izinkampani ezingama-48% zifuna ochwepheshe beJavaScript kodwa ama-42% kuphela abafundi acebile endaweni. Lokhu kusho ukuthini nje? Uma unethemba lokuthatha iJavaScript njengomsebenzi, ungangabazi. Sebenzisa ithuba bese ujoyina ubuchwepheshe obudingeka kakhulu emhlabeni bese ujoyina abanye abathuthukisi kulo mkhakha ofanayo.
Imiholo yeJavaScript Ngokusho Kwendawo.
Kuze kube manje, usuqaphele ukuthi ukuthuthukiswa kweJavaScript kuyisifundo sobuchwepheshe esidinga ubungcweti obuningi. Usuqaphele nokuthi umsebenzi ufunwa kanjani. Lokhu kuholela embuzweni, bakhokhelwa malini abathuthukisi beJavaScript abangochwepheshe? Ngokusho kwe-Indeed, okulandelayo yizibalo abathuthukisi abaziholayo minyaka yonke emhlabeni jikelele. E-United States, abathuthukisi abajwayelekile bathatha cishe u-$111,069 ngonyaka ngokusho kwe-Indeed. Abathuthukisi baseJalimane bathatha u-€58,108 ngonyaka ngokusho kwe- Glassdoor . E-India, bakhokhelwa u-₹ 5,18,875 ngonyaka ngokusho kwe-Indeed, i-United Kingdom ithatha u-£49,001 ngonyaka ngokusho kwe-Indeed.

Izinombolo ezingenhla zimele inani elitholwa unjiniyela weJavaScript ngokuya ngendawo noma indawo lapho behlala khona. Kokulandelayo, sizodlula emiholweni etholwa ngabathuthukisi beJavaScript ngokuya ngezinga labo lesipiliyoni.
Imiholo yeJavaScript isuselwa eminyakeni yesipiliyoni
Amathrendi anemisebenzi eminingi ukuthi lapho umuntu enolwazi oluningi, kulapho eba nolwazi oluningi, yingakho ethola okuningi. Lezi zibalo ezilandelayo ukuhlaziywa kwemiholo okusekelwe e-United States okuphathelene nokuthi unjiniyela onolwazi kangakanani nge-PayScale.
Ngabathuthukisi abasanda kuqala, isikhathi esingaphansi konyaka, bathola cishe ama- $ 62,973 minyaka yonke. Labo abathole ulwazi oluncane embonini njengasesikhathini seminyaka engu-4 bathola okungenani ama- $ 70,022 minyaka yonke. Onjiniyela abanolwazi okungenani lweminyaka engu-9 bathola u- $ 87,281 ngenkathi labo abanolwazi okungenani lweminyaka engu-19 behola u- $ 102,697. Kusukela kumathrendi angenhla, kusobala ukuthi lapho umuntu enolwazi oluningi, yilapho ethola imali ethe xaxa. Abathuthukisi beJavaScript abaneminyaka engaphezu kwengu-20 yesipiliyoni bathola okungenani ama- $ 113,274 minyaka yonke.
Amaholo wonjiniyela weJavaScript asuselwa kusayizi wenkampani
Ngokusho kwePayscale, kusobala ukuthi ubukhulu benkampani bunomthelela oqondile emholweni otholwa ngabathuthukisi e-United States. Izibalo ezilandelayo zibonisa ukuthi inkampani inkulu kangakanani nokuthi umakhi weJavaScript uhola malini.
Inkampani enabasebenzi abayi-9 ikhokhela abathuthukisi bayo $ 73,202 ngenkathi inkampani enabasebenzi abayi-10-49 iyikhokha, abathuthukisi, $ 72,081. Inkampani ekhulayo enabasebenzi abangafika ku-199 ikhokhelwa u- $ 78,114 kuyilapho leyo enezinombolo eziningi zabasebenzi engu-599 ingama- $ 81,377. Inkampani esezingeni eliphakathi nendawo enenani eliphakeme labasebenzi elingu-1,999 ithola cishe ama- $ 84,838. Inkampani enenani labasebenzi ebanga phakathi kuka-5,000 19,999 no-89,866 ithola cishe ama- $ 20,000. Inkampani enabasebenzi abangu-49,999 88,860-50,000 ikhokha onjiniyela bayo $ 88,650 ngenkathi inkampani enabasebenzi abangaphezu kuka-XNUMX ikhokhela abathuthukisi i- $ XNUMX
Kusukela ekuhlaziyweni okungenhla, uzobona ukuthi izinkampani ezinkulu ezinabasebenzi abaningi zivame ukukhokha onjiniyela bazo beJavaScript eziphakeme kakhulu ngokungafani nalezi ezinabasebenzi abambalwa.
