Game da daftarin aiki na WebAssembly 2.0
A wani ɓangare na canje-canjen da aka yi tun lokacin WebAssembly sune shawarwarin da aka gama don WebAssembly 2.0 su ne kafaffen nisa SIMD, ayyukan ƙwaƙwalwar ajiya, nau'in tunani, JavaScript BigInt goyon bayan WebAssembly i64, goyon baya ga ƙimar dawowa da yawa da shigo da / fitarwa na mutable. duniya masu canji.
W3C ta buga daftarin bayani na WebAssembly 2.0 guda uku:
- Babban Majalisar Yanar Gizo: yana bayyana ƙaramin injin kama-da-wane don gudanar da matsakaiciyar lambar WebAssembly. Abubuwan da ke da alaƙa da WebAssembly suna zuwa a cikin tsarin ".wasm", kama da fayilolin Java ".class", waɗanda ke ɗauke da tsayayyen bayanai da ɓangarori na lamba don aiki tare da waɗannan bayanan.
- Gidan yanar gizon JavaScript yana haɗuwa: yana ba da API don haɗawa da JavaScript. Ba ka damar samun ƙima da wuce sigogi zuwa WebAssembly ayyuka. Kisa WebAssembly yana bin tsarin tsaro na JavaScript, kuma duk hulɗar da mai watsa shiri ana yin su ta hanyar da ta dace da gudanar da lambar JavaScript.
- API na Yanar Gizo: yana bayyana API bisa tsarin Alkawari don nema da aiwatar da albarkatun ".wasm". An inganta tsarin albarkatun yanar gizo na WebAssembly don fara aiwatarwa ba tare da jiran fayil ɗin ya sauke cikakke ba, wanda ke inganta jin daɗin aikace-aikacen yanar gizo.

Har ila yau, ya kamata a lura cewa akwai wasu muhimman canje-canje a cikin WebAssembly 2.0 idan aka kwatanta da sigar farko na daidaitattun:
