MEAN yog qhov pub dawb thiab qhib qhov chaw JavaScriptsoftware pawg rau kev tsim cov vev xaib dynamic thiab web applications.js. Vim tias tag nrho cov ntsiab lus ntawm cov MEAN pawg pab txhawb nqa uas tau sau rau hauv JavaScript, MEAN daim ntawv thov tuaj yeem sau ua ib hom lus rau ob qho tib si server-sab thiab tus neeg siv khoom-sab ua haujlwm ib puag ncig.
Ib yam li ntawd, tib neeg nug, dab tsi txhais tau tias pawg hauv programming?
Lub sij hawm MEAN pawg yog hais txog kev sau ntawm JavaScript raws li thev naus laus zis siv los tsim cov ntawv thov web. MEAN yog ib lub npe luv rau MongoDB, ExpressJS, AngularJS thiab Node. js . Los ntawm cov neeg siv khoom mus rau server mus rau database, MEAN yogfull pawg JavaScript.
Ib yam li ntawd, kev txhim kho lub vev xaib txhais li cas? Kev txhim kho lub vev xaib broadly hais txog cov haujlwm uas cuam tshuam nrog txhim kho cov websites rau hosting ntawm intranetor internet. Cov kev txhim kho lub vev xaib txheej txheem suav nrog web tsim, web cov ntsiab lus kev loj hlob , client-side/server-side scripting thiab network security configuration, ntawm lwm yam hauj lwm.
Ib yam li ntawd, tib neeg nug, software txhais li cas?
Software , nyob rau hauv nws qhov kev txiav txim zoo tshaj plaws, yog ib txheej ntawm cov lus qhia lossis cov kev pab cuam qhia lub computer ua cov haujlwm tshwj xeeb. Software yog ib lo lus generic siv los piav txog computerprograms. Cov ntawv sau, cov ntawv thov, cov kev pab cuam thiab cov lus qhia yog tag nrho cov ntsiab lus feem ntau siv los piav qhia software.
Cov nyiaj hli ntawm txhais tau tias pawg tsim tawm yog dab tsi?
Qhov nruab nrab Mean Stack Developer nyiaj hli Hauv Asmeskas yog $ 121, 875 ib xyoos lossis $ 62.50 toj ib teev. Cov haujlwm nkag qib pib yog $ 40,000 toj ib xyoo thaum cov neeg ua haujlwm paub txog feem ntau tau txog $ 207, 188 toj ib xyoo.

Runtime txhais li cas hauv programming?
Runtime yog thaum lub program tab tom ua haujlwm (lossis ua tiav). Ntawd yog, thaum koj pib qhov program khiav hauv lub computer, nws yog runtime rau qhov program. Tau ntau xyoo, cov kws sau ntawv tau tawm tsam 'runtime' raws li ib lo lus, hais tias ib yam dab tsi zoo li 'thaum ib qho kev pab cuam khiav' yuav tsis xav tau lub sijhawm tshwj xeeb
Marshal txhais li cas hauv programming?
Hauv computer science, marshalling lossis marshaling yog cov txheej txheem ntawm kev hloov pauv lub cim xeeb sawv cev ntawm ib qho khoom rau cov ntaub ntawv tsim nyog rau kev khaws cia lossis kev sib kis, thiab nws feem ntau yog siv thaum cov ntaub ntawv yuav tsum tau txav ntawm ntau qhov chaw ntawm lub khoos phis tawj lossis los ntawm ib qho kev pab cuam mus rau lwm
Modular programming pab tau li cas hauv cov lus programming?
Cov txiaj ntsig ntawm kev siv modular programming suav nrog: Tsawg code yuav tsum tau sau. Ib txoj kev tuaj yeem tsim kho rau rov siv dua, tshem tawm qhov yuav tsum tau rov ntaus tus lej ntau zaus. Cov kev pab cuam tuaj yeem tsim tau yooj yim dua vim tias ib pab pawg me cuam tshuam nrog tsuas yog ib feem me me ntawm tag nrho cov cai
Dab tsi yog qhov sib txawv ntawm cov txheej txheem programming thiab modular programming?
Structured programming yog qib qis ntawm coding hauv txoj kev ntse, thiab kev ua haujlwm modular yog qib siab dua. Modular programming yog hais txog kev sib cais qhov chaw ntawm cov kev pab cuam rau hauv kev ywj pheej thiab hloov pauv tau, los txhim kho kev sim, kev tswj xyuas, kev sib cais ntawm kev txhawj xeeb thiab rov siv dua
Koj txhais li cas los ntawm kev pom qhov programming?
Visual programming yog hom lus programming uas cia tib neeg piav qhia txog kev siv cov duab kos. Txawm hais tias ib qho lus sau raws li programming lus ua rau tus programmer xav zoo li lub khoos phis tawj, cov lus pom zoo tso cai rau tus programmer piav qhia txog cov txheej txheem hauv cov ntsiab lus uas ua rau tib neeg
