JavaScript injini kuburitswa , yakanangana nekupinda mukati meiyo kodhi base yemapurojekiti mumutauro weC/C++. Iyo injini inokwana muhukuru, inotakurika zvakanyanya uye yakaderera zviwanikwa kushandiswa. Iko kunobva kodhi yeinjini yakanyorwa muC uye pasi peMIT rezinesi.
Iyo Duktape kodhi inotora kusvika 160 kB uye inongotora makumi manomwe kB eRAM, uye mune yakaderera memory yekushandisa mode 70 kB yeRAM. Kubatanidza Duktape muC/C++ kodhi wedzera mafaera duktape.c uye duktape.h kuchirongwa, uye shandisa kufonera JavaScript mabasa kubva kuC/C++ kodhi kana zvinopesana. Kusunungura zvinhu zvisina kushandiswa kubva mundangariro, muunganidzi wemarara ane finalizer anoshandiswa, akavakirwa pahwaro hwekusanganiswa. kubatanidza kuverenga nekumaka algorithm (Maka uye Tsvaira). Injini inoshandiswa kugadzirisa JavaScript mubrowser .
Inopa kuenderana kuzere neEcmascript 5.1 kutsanangurwa uye chikamu Ecmascript 2015 uye 2016 (E6 uye E7), kusanganisira Proxy chinhu chinotsigira pfuma virtualization, Typed Arrays, ArrayBuffer, Node.js Buffer, Encoding API, Symbol chinhu, nezvimwe. Inosanganisira yakavakirwa-mukati debugger, inogara ichitaura injini, uye subsystem yekutsigira Unicode. Kuwedzerwa kwakananga kunopihwawo, senge coroutine rutsigiro, yakavakirwa-mukati matanda dhizaini, CommonJS-based module yekurodha meshini, uye bytecode caching system inobvumidza iwe kuchengetedza uye kurodha mabasa akaunganidzwa.
Mukuburitswa kutsva mafoni matsva ku duk_to_stacktrace() uye duk_safe_to_stacktrace() kuti uwane mateki, duk_push_bare_array() kuwedzera akazvimirira akatevedzana zviitiko. Iwo mabasa duk_require_constructable() uye duk_require_constructor_call() akaitwa pachena. Yakavandudzwa kuenderana neiyo ES2017 yakatarwa. Kushanda nearrays uye zvinhu zvakagadziridzwa. Yakawedzerwa "-no-auto-complete" sarudzo kune duk CLI interface kudzima kupedzisa kwekuisa.
