NjengeCSS kunye ne-HTML, iJavaScript ikwajongwa njengelona lwimi lusetyenziswayo kuphuhliso lwewebhu kwihlabathi liphela. Ukuqonda okungcono, iJavaScript lulwimi lwenkqubo olongeza unxibelelwano kwiphepha lewebhu. Kuba iJavaScript iphezulu-kwiilwimi zenkqubo, umbuzo unokuvela, uthini umvuzo ophakathi weJavaScript?
Ukuze siqonde ngcono le nto, siza kuhlalutya ukuba yintoni umvuzo womphuhlisi weJavaScript size sithelekise amaxabiso kwihlabathi liphela. Kweli nqaku, siza kuhlalutya ezi zihloko zilandelayo.
- Indima yonjiniyela weJavaScript.
- Ibango labaphuhlisi beJavaScript.
- Imivuzo yonjiniyela weJavaScript ngokweendawo
- Imivuzo yonjiniyela weJavaScript esekwe kwiminyaka yamava
- Imivuzo yonjiniyela weJavaScript esekwe kwinkampani enkulu
Indima yonjiniyela weJavaScript
Abaphuhlisi beJavaScript basebenzisana nabasebenzisi kunye nabaphathi kwinkampani ukuze bahlangabezane neemfuno zabo kwaye benze utshintsho ngokwenza ngokwezifiso, uyilo, kunye nokusetyenziswa kweempawu ezintsha. Ukuze umntu abe ngumphuhlisi weJavaScript oqeqeshiweyo, kufuneka abe nokuqonda okungcono kophuhliso lweJavaScript oluphambili kwaye kufuneka abe neMySQL, ucwangciso kwiPerl , kunye nePython.
Abaphuhlisi beJavaScript bayaphendula kumphathi ophezulu wophuhliso lwewebhu osebenzisana namalungu ngaphakathi kwintengiso yedijithali, abayili bewebhu, abaphuhlisi abasemva, kunye namaqabane entengiso abelweyo.
Ukufezekisa wonke umsebenzi ochazwe apha ngasentla, abaphuhlisi beJavaScript kulindeleke ukuba babe nolwazi olwaneleyo kwezi ndawo zilandelayo:
Ulwazi olwaneleyo lwe-CSS3 kunye ne-HTML5
Kuya kufuneka uyazi i-JavaScript yemveli kwi-ES6, ES5, kunye nemicimbi yokuhambelana kwesikhangeli.
Kufuneka ube namava kwi-Angular, Vue, okanye kwi-React.
Ibango labaphuhlisi beJavaScript
Ukusuka kwezi nkcazo zingasentla, umntu uyakuqonda ukuba umphuhlisi weJavaScript uphakathi kwezona zikalwe ehlabathini kwiilwimi zenkqubo kwihlabathi liphela. Ngokwengxelo yeDevskiller 2019, kwiindlela ezivelayo, baqaphela ukuba iipesenti ezingama-70 zeenkampani zifuna abaphuhlisi beJavaScript. Oku kubonisa ukuba zingakanani ezi zakhono ziphezulu.
Kolunye uphando olwenziwe yiHackerRank , bahlalutye baza bagqiba kwelokuba imfuno yabaphuhlisi beJavaScript idlula iingcali ezikhoyo kweli candelo. Ngokohlalutyo lwabo, ama-48% eenkampani afuna iingcali zeJavaScript kodwa ama-42% kuphela abafundi abacebileyo kweli candelo. Oku kuthetha ukuthini nje? Ukuba unethemba lokuthatha iJavaScript njengomsebenzi, ungathandabuzi. Sebenzisa eli thuba kwaye ujoyine ulwazi olufunekayo kwihlabathi kwaye ujoyine abanye abaphuhlisi kweli candelo.
Imivuzo yeJavaScript ngokweNdawo.
Ukuza kuthi ga ngoku, sele uqonda ukuba uphuhliso lweJavaScript luyinto yobugcisa efuna ubuchule obuninzi. Ukwaqonda nokuba kufuneka umsebenzi onjani. Oku kukhokelela kumbuzo othi, bahlawulwa malini abaphuhlisi beJavaScript abangochwephesha? Ngokutsho kwe-Indeed, la manani alandelayo afunyanwa ngabaphuhlisi minyaka le kwihlabathi liphela. E-United States, abaphuhlisi abaqhelekileyo bathabatha malunga ne-$111,069 ngonyaka ngokutsho kwe-Indeed. Abaphuhlisi baseJamani bathabatha i-€58,108 ngonyaka ngokutsho kwe- Glassdoor . E-India, bahlawulwa i-₹ 5,18,875 ngonyaka ngokutsho kwe-Indeed, i-United Kingdom ifumana i-£49,001 ngonyaka ngokutsho kwe-Indeed. E-Australia, bahlawulwa i-$112, 229 ngonyaka ngokutsho kwe-Indeed, kwaye eMzantsi Afrika iyonke i-R472 710 ngelixa eCanada umvuzo wabo uyi-$82, 786 ngokutsho kwe-Indeed.
La manani angentla amele imali efunyanwa ngumqambi weJavaScript ngokwendawo okanye indawo abahlala kuyo. Kwilandelayo, siya kudlula kwimivuzo efunyanwa ngabaphuhlisi beJavaScript ngokusekwe kwinqanaba labo lamava.
Imivuzo yeJavaScript esekwe kwiminyaka yamava
Iindlela ezihamba kunye nemisebenzi emininzi kukuba umntu onamava ngakumbi, kokukhona bafumana amava ngakumbi, yiyo loo nto bafumana umvuzo ongaphezulu. La manani alandelayo luhlalutyo lwemivuzo esekwe e-United States enxulumene nokuba unamava njani umphuhlisi weJavaScript ngokwePayScale.
Kubaphuhlisi abaqala ukuqala, kangangexesha elingaphantsi konyaka, bafumana umvuzo malunga ne-62,973 yeedola ngonyaka. Abo bafumene amava kolu shishino njengakwisithuba seminyaka emi-4 bafumana ubuncinci i-70,022 yeedola ngonyaka. Abaphuhlisi abaneminyaka engama-9 yamava bafumana i-87,281 yeedola ngelixa abo banamava ubuncinci beminyaka eyi-19 bafumana i-102,697 yeedola. Ukusuka kwezi ntsingiselo zilapha ngasentla, kuyacaca ukuba okukhona umntu enamava, kokukhona bafumana okungakumbi. Abaphuhlisi beJavaScript abangaphezulu kweminyaka engama-20 yamava bafumana ubuncinci i-113,274 yeedola rhoqo ngonyaka.
Imivuzo yonjiniyela weJavaScript esekwe kubungakanani benkampani
NgokukaPayscale, kuyacaca ukuba ubungakanani benkampani bunempembelelo ethe ngqo kumvuzo ofunyanwa ngabaphuhlisi eMelika. La manani alandelayo abonisa ukuba inkulu kangakanani inkampani kwaye ingakanani imali ayifumana kumakhi weJavaScript.
Inkampani enabasebenzi abali-9 ihlawula abaphuhlisi bayo i-73,202 yeedola ngelixa inkampani enabasebenzi abayi-10-49 ihlawula, abaphuhlisi, i-72,081 yeedola. Inkampani ekhulayo enabasebenzi abali-199 ababhatalwayo ihlawulwa i-78,114 yeedola ngelixa eyona inenani labasebenzi abangama-599 ingama-81,377 eedola. Inkampani ekumgangatho ophakathi nenani eliphezulu labasebenzi abayi-1,999 ifumana malunga ne- $ 84,838. Inkampani enenani labasebenzi eliphakathi kwama-5,000 19,999 no-89,866 lifumana imali eyi- $ 20,000. Inkampani enabasebenzi abangama-49,999-88,860 ihlawula abaphuhlisi bayo i-50,000 yeedola ngelixa inkampani enabasebenzi abangaphezu kwama-88,650 ihlawula abavelisi bayo i-XNUMX yeedola
Ukusuka kuhlalutyo olungentla, uya kuqaphela ukuba iinkampani ezinkulu ezinabasebenzi abaninzi zihlala zibhatala abaphuhlisi bazo beJavaScript ziphakamile ngokungafaniyo nabasebenzi abambalwa.
