Object Oriented Programming ( OOP ) yog hais txog kev siv tus kheej cov ntawv ntawm cov lej los tsim cov ntawv thov. Peb hu cov ntawv no tus kheej muaj cov cai khoom , zoo dua lub npe hu ua Classes nyob rau hauv feem ntau OOP programming lus thiab Kev Ua Haujlwm hauv JavaScript . Peb siv khoom raws li lub tsev blocks rau peb daim ntawv thov.
Ntawm no, txhais li cas los ntawm Object Oriented Programming?
Yam khoom - oriented programming ( OOP ) hais txog ib hom computer programming (software design) uas programmers txhais cov ntaub ntawv hom ntawm cov ntaub ntawv qauv, thiab kuj yog hom kev ua haujlwm (functions) uas tuaj yeem siv rau cov qauv ntaub ntawv.
Ib yam li ntawd, qhov txawv ntawm JavaScript thiab cov khoom taw qhia Javascript yog dab tsi? Javascript yog yam khoom raws li . Object Oriented yog raws ntawm kev xa xov, tsis muaj cov chav kawm lossis qhov qub txeeg qub teg koom nrog. " Khoom taw qhia " coined los ntawm Dr Alan Kay tau raug nyiag los ntawm C ++, Java thiab Co, Dr Alan Kay tau hais meej tias OO yog cov lus, tsis yog chav kawm.
Ua raws li qhov no, peb puas tuaj yeem siv OOPS hauv JavaScript?
JavaScript yog ib hom lus zoo heev los sau cov khoom oriented web applications. Nws ua tau txhawb OOP vim nws txhawb nqa qub txeeg qub teg los ntawm prototyping nrog rau cov khoom thiab cov txheej txheem. Muaj ntau developers raug ntiab tawm JS raws li hom lus OOP tsim nyog vim lawv yog yog li siv rau chav kawm style ntawm C# thiab Java.
Puas yog JavaScript OOP lossis ua haujlwm tau?
JavaScript tsis yog ib yam khoom-oriented los yog functional programming lus. Nws yog lus txheej txheem. Yog, nws muaj kev txhawb nqa rau Object-oriented programming (OOP ) siv prototypes. Txawm li cas los xij, prototypes tsis yog ib txoj hauv kev los ua OOP.

Dab tsi yog qhov txawv ntawm me ntsis oriented thiab byte oriented raws tu qauv?
Bit oriented Protocol-: Me ntsis oriented raws tu qauv yog ib qho kev sib txuas lus raws tu qauv uas pom cov ntaub ntawv xa mus raws li ib tug opaque kwj ntawm tom uas tsis muaj symantics, los yog lub ntsiab lus, tswj cov lis dej num yog txhais nyob rau hauv lub sij hawm khoom. Byte Oriented Protocol tseem hu ua tus cwj pwm - Oriented Protocol
Puas yog C ++ object oriented los yog txheej txheem?
C ++ feem ntau suav hais tias yog 'multi-paradigm'language. Ntawd yog, koj tuaj yeem siv nws rau kev taw qhia txog kev ua haujlwm, txheej txheem, thiab kev ua haujlwm sib luag. Cov neeg uas yuav tsis lees paub tias C ++ yog OOgenerally muaj nqaij nyug nrog qhov tseeb tias cov hom qub tsis yog lawv tus kheej
Puas yog Java object oriented lossis object based?
Java yog ib qho piv txwv ntawm object-oriented programing lus uas txhawb kev tsim thiab kev txais qub txeeg qub teg (uas yog rov siv cov lej) ib chav kawm los ntawm lwm tus. VB yog lwm qhov piv txwv ntawm hom lus raws li koj tuaj yeem tsim thiab siv cov chav kawm thiab cov khoom siv tab sis tsis muaj kev txhawb nqa
Puas yog object oriented programming haum rau graphical applications?
OOP yog qhov tsim nyog rau daim ntawv thov duab. Feem ntau ntawm OOPs cov tsev qiv ntawv cov lus tau nyiam tshaj qhov tsis yog OOP cov tsev qiv ntawv cov duab nraaj vim lawv pab ua kom muaj peev xwm thiab khaws tau daim ntawv thov thiab pab txhawb kev rov siv Code
Dab tsi yog object oriented programming thiab nws cov yam ntxwv?
Cov yam ntxwv ntawm OOPare: Abstraction - Qhia meej tias yuav ua li cas tab sis tsis ua li cas; ib tug saj zawg zog feature kom muaj ib tug zuag qhia tag nrho saib ntawm anobject lub functionality. Encapsulation - Kev khi cov ntaub ntawv thiab kev ua haujlwm ntawm cov ntaub ntawv ua ke hauv ib chav tsev - Ib chav kawm ua raws li qhov tshwj xeeb no
