Konsorciumi W3C shpalli gatishm\u00ebrin\u00eb e specifikacionit q\u00eb standardizon kodin e nd\u00ebrmjet\u00ebm WebAssembly 3.0 dhe API-n\u00eb p\u00ebrkat\u00ebse, duke lejuar krijimin e aplikacioneve me performanc\u00eb t\u00eb lart\u00eb, t\u00eb transportueshme midis shfletuesve dhe platformave harduerike. WebAssembly ofron nj\u00eb kod t\u00eb nd\u00ebrmjet\u00ebm universalisht t\u00eb ul\u00ebt q\u00eb nuk varet nga shfletuesi p\u00ebr ekzekutimin e aplikacioneve, duke u compiluar nga gjuh\u00eb t\u00eb ndryshme programimi. <\/p>\n
