Ukusebenza-kweSafari-Java-Nitro-0

I-Safari ayifumananga kuhlaziyo lwentsebenzo ixesha elide emva kokuba uMavericks ephume no "kancinane" kuyilo ngokutsha lomdibaniso wesikhangeli kwaye ezinye iimpawu ezongezelelweyo njengoluhlu lokufunda oluqhubeka ukusuka kufundo olunye ukuya kolunye ngotshintsho olugudileyo kunye nezilungiso ezincinci.

Ngoku ngokolwazi olwahlukileyo, iApple iyakuba njalo ukusebenza ngokwandisa ukusebenza IJavaScript eSafari. Injini yesikhangeli esivulekileyo esekwe kwisikhangeli sika-Apple, iWebKit "Nitro", iyahlaziywa kwaye iphuculwe ukukhuphisana ngentloko nezinye izindululo ezinje ngeChannel ngenjini yayo yeJavascript "V8" okanye evela kwiMozilla FireFox ene "SpiderMonkey" ".

Olu hlaziyo lutsha kule injini ikhankanyiweyo ye-WebKit "Nitro" yeJavaScript aziwa njenge «FTLJIT«. Kwelinye icala isathathelwa ingqalelo kuvavanyo, kwaye ngenxa yoko, ayisebenzi ngokungagqibekanga, endaweni yoko kufuneka yenziwe yenziwe ngokhetho lwelayini yomyalelo.

Uphawu olunokwenza FTLJIT Yima ngaphandle nangakumbi, yindlela eyiyo esebenza ngayo ikhowudi yeJavaScript engalungiselelwanga ngokuthe ngqo i-asm.js., eyilwe nguMozilla ukuze baleka kwiSpiderMonkey ngolwaziso oluthile lwale njineli nangoku kungoku kukho omnye umphuhlisi wesikhangeli okhethe ukulandela ukukhokelwa yiMozilla.

Iingxelo zithi nge-WebKit kunye ne-FTLJIT ikwenzile ukuba ukwazi uqhuba uChannel kwiimvavanyo ezikhawulezileyo, nangona kunjalo iFirefox isaziphakamisile iitshathi isebenzisa iibenchmark ezenziwe kwi-asm.js.

IJavaScript ivumela iintlobo ze Unxibelelwano lomsebenzisi kunye nephepha lewebhu, evumela imisebenzi enjengokuphinda kulayishwe kwakhona ulwazi ngaphandle kokuphinda ulayishe iphepha lonke lewebhu. Kananjalo, ukusebenza kwenjini yeJavaScript kunokuba nefuthe elikhulu kumava omsebenzisi.

Kukwanje akukho umhla Olu hlaziyo lwenjini ukubona ukukhanya kunye nokudityaniswa ngokusisigxina kwiSafari.

    IJava ayinanto yakwenza neJavaScript. Ke umfanekiso weJava kunye nesihloko zininzi kakhulu.

    PS Uxolo ngezandi, ndibhala kwikhibhodi yesiNgesi.
