Kodi Scala Ali Okonzeka Kuti Alowe Kwambiri?
Zatsopano zamakono zamakono zimaphatikizapo kusamalidwa kwazinenero zamakono. Chilankhulo chimodzi chomwe chikuwoneka chokonzeka kusamalira kwambiri ndi Scala. Ngakhale kuti sizinatchulidwebe, Scala akuwoneka kuti akupeza phindu lokhazikitsa pakati pa mawu ovomerezeka a Ruby ndi chithandizo champhamvu cha Java. Nazi zifukwa zingapo zomwe Scala angafunike kuyang'ana kachiwiri.
Imathamanga pa Java Virtual Machine
Chowonadi cha mapulogalamu ochita malonda ndikuti Java ndilo lotchuka kwambiri m'chinenero. Komanso, mabungwe ambiri akuluakulu adzakhala pangozi yotsutsana ndi kukonzanso ndondomeko yonse ya mapulogalamu. Scala ingapereke malo abwino pakati apa, chifukwa ikugwiritsabe ntchito pa JVM. Izi zikhoza kulola Scala kusewera bwino ndi zida zambiri zogwiritsira ntchito zomwe zingakhalepo kale pa bizinesi, zomwe zimapangitsa kuti anthu asamukireko pang'ono.
Scala imakhalanso ndi mwayi waukulu kwambiri wosagwirizana pakati pawo ndi code Java yomwe ilipo. Ngakhale ambiri anganene kuti izi sizowonongeka, zoona zake ndi zovuta kwambiri. Ngakhale zili choncho, zikhoza kunenedwa kuti Scala akhoza kusewera bwino ndi Java kusiyana ndi zinenero zina zambiri.
Kugwiritsiridwa ntchito kwa JVM ndi Scala kungathandizenso kuthetsa mavuto onse omwe anthu akuda nkhawa angasamukire. Amagwiritsa ntchito pulojekiti yofanana ya Java, choncho pulogalamu yamakampani sizinayenera kugwedezeka ndi sewero la Scala. Ndiponso, Scala imalola kugwiritsa ntchito makanema ambiri a JVM, omwe kawirikawiri amakhala omangiriza kwambiri mu khodi lamalonda. Mwanjira iyi, Scala ikhoza kukhala khoma labwino la bizinesi yomwe ilipo Java.
Ndizovuta Kwambiri ndi Zowoneka kuposa Java
Scala imagawana zinthu zambiri zosavuta, zosawerengeka zomwe zimapezeka m'zinenero zambiri monga Ruby. Ichi ndi chinthu chomwe sichipezeka ku Java ndipo chimakhudza kwambiri ntchito ya gulu la chitukuko mu kukonza makalata. Ntchito yowonjezera yofunika kuti mumvetse ndi kusunga kachidindo ka Java komweko kuli ndalama zambiri.
Kuonjezera apo, kukongola kwa Scala kuli ndi phindu lochuluka. Scala kawirikawiri inalembedwa mu chigawo chochepa cha mizere yofunikira kulembera ntchito yofanana ku Java. Izi zimapindulitsa pothandiza omanga kuchita ntchito yowonjezera tsiku lopatsidwa ntchito. Kuwonjezera apo, mizere yochepa ya ma code imapangitsa kuti muyesedwe mosavuta, kukambiranso kachidindo ndi kukonza machitidwe.
Zochita Zogwira Ntchito
Scala imagwiritsa ntchito shuga yambiri yogwira ntchito yomwe yakhala yotchuka ndi omanga ndipo imapangitsa anthu ambiri opanga chizindikiro kuti Scala monga chinenero chogwira ntchito. Chitsanzo chimodzi ndi chitsanzo chofanana, kuti chingwe chophweka chiyereke. Chitsanzo china ndi zosakaniza, zomwe zimapereka ntchito kuti zikhale monga gawo la tanthauzo la kalasi, zomwe zingasunge nthawi yochuluka mwa kugwiritsa ntchito kachidindo. Zizindikiro ngati izi nthawi zambiri zimakhala zokongola kwa omanga, makamaka ngati akhala akuzoloŵera ntchito zawo m'malo ena omwe siali Java.
Kuphweka Kuphunzira ndi & # 34; zokondweretsa & # 34;
Zofanana za Scala ndi zilembo zamakono monga Ruby zimawoneka ngati zopindulitsa, monga momwe kufotokozera kwake kumapangitsa kuti zikhale zophweka kuphunzira, makamaka poyerekeza ndi zinenero zowonjezereka monga Java ndi C ++. Chilendo ndi chiyanjano cha chinenero chasandutsa chisankho chodziwika ndi gulu laling'ono, lolimbikitsidwa la omanga.
"Chisangalalo" chimenechi sichiyenera kuchepetsedwa, ndithudi, chingakhale chopindulitsa kwambiri pa kusamukira ku Scala. Kudalirika ndi ukalamba wa Java zimapanga chisankho chodziwika bwino pa malonda, komanso amakopeka ndi omasulira ena, omwe ali ndi vuto linalake. Zinenero zofanana ndi Scala zimatha kukopa otchuka kwambiri omwe ali "olankhula chinenero." Okonzansowa nthawi zambiri amasinthasintha, amayesetsa kuyesa zinthu zatsopano, zatsopano komanso zusowa kwambiri. Kwa mabungwe ambiri, izi zikhoza kukhala chomwe chiri chofunika pa timagulu ta chitukuko.
Ngakhale ayi Scala adzawona kuti anthu ambiri akudziwika kuti alipo, monga momwe ziliri ndi chinenero chilichonse chomwe chili ndi alaliki awo ndi osokoneza. Chowonadi ndi chakuti chisankho chothawira ku Scala ndi munthu mmodzi, ndipo chimadalira kwambiri chilengedwe. Komabe, ubwino wotchulidwa pamwambawu ukhoza kuwonetsa mkhalidwe, makamaka pa ntchito yodalirika ya Java.
