Inguqulelo entsha yenjini yeJavaScript efakwe kumseki weQEMU kunye neFFmpeg

Isazi sezibalo saseFransi uFabrice Bellard, owaseka iiprojekthi ze-QEMU kunye ne-FFmpeg, upapashe ukuhlaziywa kwi-injini ye-JavaScript edibeneyo eyaphuhliswayo. QuickJS. Injini ixhasa ukucaciswa kwe-ES2019 kunye nezandiso ezongezelelweyo zemathematika ezifana neentlobo zeBigInt kunye neBigFloat. Ukusebenza kwe-QuickJS kuyabonakala ingaphezulu kwe iianalogu ezikhoyo (XS kwi-35%, DukTape ngaphezulu kokuphindwe kabini KwiJerryScript kathathu kwaye MuJS kasixhenxe). Iprojekthi ibonelela ngethala leencwadi lokufakela injini, itoliki ye-qjs yokusebenzisa ikhowudi yeJavaScript ukusuka kumgca womyalelo, kunye ne-qjsc compiler yokuvelisa iifayile ezisebenzisekayo ezizimeleyo. Ikhowudi ibhalwe kwi-C kunye isasazwa ngu phantsi kwelayisenisi ye-MIT. Unokufunda ngakumbi malunga neprojekthi kwisicatshulwa isaziso sopapasho lokuqala.

Inguqulelo entsha yongeza inkxaso yovavanyo yohlobo Idesimali Enkulu, ekuvumela ukuba usebenzise amanani edesimali ngokuchaneka okungafunekiyo (ngokufanayo neBigInt yamanani anesiseko se-10). Ukuphunyezwa okuhlaziyiweyo kokulayisha ngaphezulu komsebenzisi. Yongeziwe imizekelo iinkqubo zokubala ngokufanelekileyo i-Pi ngokuchaneka ukuya kuthi ga kwibhiliyoni yeendawo zedesimali (njengengcali yezibalo, uFabrice Bellard waziwa njengomyili wefomula ekhawulezayo yokubala iPi).
