Konsorciumi W3C publikoi draftin e specifikimit t\u00eb ri, q\u00eb standardizon kodin e mes\u00ebm WebAssembly 2.0 dhe API-n\u00eb e lidhur, duke lejuar krijimin e aplikacioneve me performanc\u00eb t\u00eb lart\u00eb, t\u00eb transferueshme midis shfletuesve dhe platformave harduerike. WebAssembly ofron nj\u00eb kod t\u00eb p\u00ebrgjithsh\u00ebm t\u00eb ul\u00ebt, t\u00eb pavarur nga shfletuesi, p\u00ebr ekzekutimin e aplikacioneve t\u00eb komiluara nga gjuh\u00eb t\u00eb ndryshme programimi. Duke shfryt\u00ebzuar JIT p\u00ebr WebAssembly, mund t\u00eb arrihet nj\u00eb nivel performance af\u00ebr kodit natyror. <\/p>\n
Teknologjia WebAssembly mund t\u00eb p\u00ebrdoret p\u00ebr ekzekutimin n\u00eb shfletues t\u00eb detyrave q\u00eb k\u00ebrkojn\u00eb performanc\u00eb t\u00eb lart\u00eb, si kodimi i videove, p\u00ebrpunimi i z\u00ebrit, manipulimi me grafik\u00eb dhe 3D, zhvillimi i lojrave, operacioneve kriptografike dhe llogaritjeve matematikore p\u00ebrmes organizimit t\u00eb ekzekutimit t\u00eb kodit n\u00eb shfletues, t\u00eb shkruara n\u00eb gjuh\u00eb t\u00eb komiluara, si C\/C++. <\/p>\n
Mes detyrave kryesore t\u00eb WebAssembly, spikasin sigurimi i transferueshm\u00ebris\u00eb, parashikueshm\u00ebris\u00eb s\u00eb sjelljes dhe identitetit t\u00eb ekzekutimit t\u00eb kodit n\u00eb platforma t\u00eb ndryshme. S\u00eb fundmi, WebAssembly po promovohen gjithashtu si nj\u00eb platform\u00eb universale p\u00ebr ekzekutimin e sigurt t\u00eb kodit n\u00eb \u00e7do infrastruktur\u00eb, sisteme operative dhe pajisje, pa u kufizuar vet\u00ebm n\u00eb shfletues. <\/p>\n
W3C publikoi tri specifikime paraprake t\u00eb WebAssembly 2.0: <\/p>\n
\n
WebAssembly Core \u2014 p\u00ebrshkruan nj\u00eb makin\u00eb virtuale n\u00eb nivel t\u00eb ul\u00ebt p\u00ebr ekzekutimin e kodit t\u00eb nd\u00ebrmjet\u00ebm WebAssembly. Burimet e lidhura me WebAssembly ofrohen n\u00eb formatin \u2018.wasm\u2019, i ngjash\u00ebm me skedar\u00ebt \u2018.class\u2019 n\u00eb Java dhe p\u00ebrmban t\u00eb dh\u00ebna statike dhe segmente kodi p\u00ebr pun\u00eb me k\u00ebto t\u00eb dh\u00ebna. <\/li>\n
WebAssembly JavaScript Interface \u2014 ofron API p\u00ebr integrimin me JavaScript. Lejon marrjen e vlerave dhe kalimin e parametrave n\u00eb funksionet WebAssembly. Ekzekutimi i WebAssembly \u00ebsht\u00eb n\u00eb p\u00ebrputhje me modelin e siguris\u00eb s\u00eb JavaScript, dhe t\u00eb gjith\u00eb bashk\u00ebveprimi me sistemin kryesor zhvillohet n\u00eb p\u00ebrputhje me ekzekutimin e kodit JavaScript. <\/li>\n
WebAssembly Web API \u2014 p\u00ebrcakton nj\u00eb nd\u00ebrfaqe programore t\u00eb bazuar n\u00eb mekanizmin Promise p\u00ebr t\u00eb k\u00ebrkuar dhe ekzekutuar burimet \u2018.wasm\u2019. Formati i burimeve WebAssembly \u00ebsht\u00eb optimizuar p\u00ebr fillimin e ekzekutimit, pa pritur ngarkimin e plot\u00eb t\u00eb skedarit, \u00e7ka lejon rritjen e p\u00ebrgjegjshm\u00ebris\u00eb s\u00eb aplikacioneve web. <\/ul>\n
Ndryshimet kryesore n\u00eb WebAssembly 2.0 n\u00eb krahasim me versionin e par\u00eb t\u00eb standardit: <\/p>\n

Mb\u00ebshtetje p\u00ebr kthimin e disa vlerave nga blloqet dhe funksionet (p\u00ebrve\u00e7 kalimit t\u00eb disa parametrave n\u00eb funksione).\n
Realizimi i funksioneve JavaScript BigInt64Array dhe BigUint64Array p\u00ebr konvertimin midis llojit BigInt t\u00eb JavaScript-it dhe p\u00ebrfaq\u00ebsimit t\u00eb numrave t\u00eb plot\u00eb 64-bit n\u00eb WebAssembly.\n
